WOWSA 2.27 – The Recorder shall report any violations by the athletes to the Referee on a signed document detailing the rule infringement. Either the Referee or the Recorder shall inform the athlete(s) of the rule infringement.
WOWSA 2.28 – The Observer shall be responsible for documenting the event, solo swim or relay and completing the Observer Report. The Observer shall witness the event, solo swimmer or relay members and document the activities as detailed as possible. The Observer shall also be responsible for the adjudication of the rules.
WOWSA 3.1 – All escort and safety craft shall refrain from navigating through a pack of athletes at all times unless the recognized safety personnel must respond to an emergency. If any escort or safety craft impedes another athlete, the escort boat’s athlete will be immediately disqualified.
WOWSA 3.2 – Athletes may wear any number of swim caps, goggles, heart rate monitors, wristwatches, protective swimwear (including full-length swimsuits), and wetsuits of any thickness or composition as the event permits. However, awards must be separately offered for athletes who wear only FINA-legal swimsuits, one swim cap, goggles and/or ear and/or nose plugs.
WOWSA 3.3 – Athletes may use fins, snorkels, swim streamers, Shark Shields® or other shark repellent or protective equipment, hand paddles, safety rings, booties or any kind of Swimmer Safety Devices as they require or desire and which is allowed by the local governing body or race director. However, athletes using these types of equipment shall not be eligible for the same awards as athletes who wear only FINA-legal swimsuits, one swim cap, goggles and/or ear and/or nose plugs.
WOWSA 3.4 – Athletes may wear any type of sunscreen or skin lubrication including lanolin, Vaseline® or any other kind of commercial skin protection on any part of their body.
WOWSA 3.5 – Athletes are encouraged to remove jewelry, necklaces, rings, and wristwatches during the event. The Referee may require removal of all jewelry including wristwatches and rings during the race if he so wishes.
WOWSA 3.6 – The course is best marked with a combination of Turn Buoys and Guide Buoys of different colors, sizes and shapes on the course if possible. The Turn Buoys should be larger and more easily seen as these buoys indicate a turn or change of direction and can only be navigated on either the left side or right side of the athletes. The Guide Buoys should be smaller as these buoys are simply aids in helping swimmers understand the course layout. The Guide Buoys can be navigated on either side by the athletes. If possible, the Turn Buoys should be marked consecutively by numbers in the case of a point-to-point course.
WOWSA 3.7 – WOWSA encourages its sanctioned events to use timing systems with transponders or timing chips. If such a system is not used, stopwatches with memory and print out capability are strongly encouraged.
WOWSA 3.8 – WOWSA encourages its sanctioned events to use a video-recording device at the start of the event to record the athletes getting into the water. It also encourages use of a video-recording device at the finish of the event.
WOWSA 3.9 – WOWSA encourages the use of social media and pre- and post-race press releases to promote its sanctioned events. It encourages press releases that include photographs and the official results of at least the top 5 in each division.
WOWSA 3.10 – WOWSA encourages the use of aerial photography and videography of its sanctioned events to provide to the media.
WOWSA 3.11 – Athletes are permitted to carry their own fuel (e.g., gel packs) in their swimsuits or swim caps.
WOWSA 4.1 – Open Water Safety: Many Rules, Different Venues, One Goal. There are numerous rules, interpretations and traditions – local, regional, national and international – that dictate and influence the safety procedures, guidelines and rules used in open water swims, but there is only one goal: safety for all.
WOWSA 4.2 – Every open water swimming course is different and every open water swimming course can be different from day-to-day and from hour-to-hour. Safety plans, procedures and protocols may be difficult and challenging, but they should also be based on common sense and local knowledge of the waterways and the accumulated wisdom of local safety experts including lifeguards, fishermen, government authorities, boaters, and the Race Director and Safety Officer.
WOWSA 4.3 – Because the natural elements in the water and the weather are so dynamic and unpredictable, the ultimate safety of open water swimmers depends on rules and guidelines supported by common sense and a reasonable, flexible approach to safety that is properly planned, documented, approved and executed by the race director, the race organization staff and local authorities (in the case of a race) or by the coach and pilot (in the case of a solo marathon swim).
WOWSA 4.4 – Considerations may slightly differ between a limited field of professional swimmers and large fields for amateur races, between solo swims and competitions, and between events in the world’s oceans, seas, lakes, fjords, bays, rivers, reservoirs, lagoons or canals, but (1) there should be a pair of eyes potentially on every swimmer at every point in the race, and (2) there should be no blind spots along the course.
WOWSA 4.5 – At any point in the race, someone (race officials, lifeguards, volunteers or spectators) should potentially be able to see every swimmer in the water at all times. This does not mean that every swimmer should always have a pair of eyes glued on them. It only means that IF a swimmer has to be located at any point in time, there is someone in position to see them along the course. In other words, if there are points along the course where athletes cannot be seen (blinds spots) by someone, then the WOWSA Open Water Safety rules are not followed.
WOWSA 4.6 – When an athlete cannot answer simple questions about himself (e.g., his telephone number, his pet’s name, his street address), his mental state is adversely affected by the elements (e.g., heat or cold or exhaustion). Race officials should immediately pull the athlete out of the water. Even if athletes protest about being pulled from the water, the authority of the race officials is final.
WOWSA 4.7 – Lead boats either watch the lead pack of athletes with referees or race officials on board, or the lead boats actually lead the fastest swimmers along the course.
WOWSA 4.8 – Other official boats and safety marshals along the course, including safety kayakers, paddlers, surf skiers or stand-up paddlers, must keep an eye out for the middle-of-the-pack and trailing swimmers.
WOWSA 4.9 – Safety kayakers, paddlers, surf skiers and stand-up paddlers should always scan the field. These safety staff should possess a means of communication and understand the communication chain to alert the swimmers and officials if there are problems or emergencies.
WOWSA 4.10 – Numbering of athletes is essential to enable the race organization and timing company to keep track of the athletes in the water and at the end of the race. Numbers can be hand-written or stamped with ink pads on the athlete’s hands, arms, backs or swim caps. Alternatively, the numbers can placed on the vests or clothing used by the athlete’s kayaker, paddler or stand-up paddler.
WOWSA 4.11 – Athletes and safety personnel shall use night sticks, glow sticks, disc lights, or some other form of adequate illumination in order to identify an athlete in low-light conditions or in the dark, especially during solo swims or relays. Similarly, escort kayakers, paddlers and/or boaters shall also have different types of illumination on their body or equipment in order for the athletes to see them.
WOWSA 4.12 – Positioning of safety personnel on the course shall be determined by the Race Director and Safety Officer based on their experience, dynamic conditions of the course, historical considerations, and the experience of the local government officials and safety personnel. Safety personnel should always be positioned along the course in a variety of pre-determined positions. They are assigned specific areas to patrol with adequate communication tools to alert others and the command control.
WOWSA 4.13 – Safety personnel and course marshals should be easily identified by each other, the athletes, and the spectators at the competition. The communication between the Race Director, Safety Officer, and all safety personnel on land and in the water should be convenient and easily performed through the use of radios or mobile phone.
WOWSA 4.14 – Open water swimming is a sport inherent with risks. There are risks from marine life, from currents and tidal flows, from exhaustion, from hypothermia and hyperthermia, and from collisions with piers, docks, pontoons, feeding stations, escort boats, kayakers and surf skis. The more eyes on the swimmers in the open water, the safer the swimmers generally are. A Race Director actively engages the assistance of four different levels of safety:
WOWSA 4.14.1 – The highest level of open water safety responsibility falls on the race organization staff that creates structures, provides equipment, sets the philosophy and plans, prepares and prioritizes safety well before race day. This includes contracted staff such as lifeguards, Safety Officers, volunteer medical personnel, local lifeguards, fishermen and boaters who know the body of water best. Consultation with all of these different groups falls upon the shoulders of the race director and staff.
WOWSA 4.14.2 – Race volunteers stationed along the course, both on the water and on shore, provide the second set of eyes on the swimmers. These volunteers are provided pre-race instructions on what to do when problems or emergencies occur and are provided with whistles, binoculars and mobile communication devices.
WOWSA 4.14.3 – Spectators on shore can also help. The race announcer keeps the spectators on shore engaged by calling attention to everyone on the course, from the fastest to slowest swimmers. Through the voice of the announcer, the eyes of the spectators can be directed to scan the course that serves to increase the safety net.
WOWSA 4.14.4 – The athletes themselves are often the first to respond to a fellow swimmer in need. During pre-race instructions, all athletes should be told how to call for help and where that help will be located (in boats, on kayaks, JetSkis, surf skis or paddle boards, on shore, with radios, dressed in red or other identifiable colors). While a Race Director cannot depend on the athletes in the water, these athletes are often an active and first line of defense.
WOWSA 4.15 – WOWSA recommends to Race Directors that they look at safety from four perspectives: Philosophy, Planning, Preparation, and Priority.
WOWSA 4.15.1 – The WOWSA philosophy that safety for the athletes is the top priority must be genuine because there are inherent risks in the sport. If budgets cannot allow for proper safety measures to be taken, then the event shall not be held. If human resources are inadequate to provide proper safety measures to be taken, then the event shall not be held. If equipment (watercraft, radios, and emergency medical facilities) is inefficient, then the event shall not be held.
From a positive perspective, a philosophy of safety must be pervasive from the very moment a race is conceived. The focus on safety is set by the Race Director and Safety Officer and needs to be on the mind of every race volunteer and organization personnel. Budgets, watercraft (boats, kayaks, Inflatable Rescue Boats (IRBs), surf skis, personal watercraft (PWC), paddle boards), volunteers, professionals (lifeguards, physicians, paramedics) and equipment must be part of the planning process from Day One.
WOWSA 4.15.2 – When a race is in the planning stages, safety aspects and considerations are paramount. A general idea of the number of safety personnel will be derived from the estimated number of athletes. A general idea of the optimal type and number of watercraft (diesel boats, kayaks, IRBs, PWCs, paddle boards, stand-up paddlers, JetSkis) to use will also be derived by the configuration and location of the race. The assumed water and weather conditions will determine the type and number of onshore personnel and equipment (mylar blankets, whistles, radios).
A communication plan shall be prepared so every individual involved in the race organization knows what their roles are and where and what they should be doing during contingencies or in emergencies. Emergency plans shall be prepared that documents assigned responsibilities, actions and procedures required in the event of an emergency. Additionally, a written Athlete’s Guide shall be a useful tool to educate and inform the athletes of what is expected and all the different situations that can occur.
WOWSA 4.15.3 – The Athlete’s Guide shall be posted on the event website and emailed to the athletes well in advance of race day. The Athlete’s Guide should provide helpful tips and reminders for the athlete regarding water temperature, water conditions and course layout and how they can prepare for these expectations.
WOWSA 4.15.4 – After all the plans have been discussed and documented, the written plans must be prepared to be executed. Emailing safety plans to key staff and volunteers is important, but even more important are face-to-face meetings where everyone is informed on what can happen on race day, review contingency plans, discuss emergency situations, test everyone’s knowledge of how to communicate, where to go and what to do when the unexpected occurs.
WOWSA 4.15.5 – Race Directors should prepare notes to keep on a clipboard with information for easy and quick reference. Similar to the land-based safety personnel, volunteers and staff on the water should be given the same information prepared in waterproof bags.
WOWSA 4.16 – On race day, the Race Director should be prepared to change things on the fly without hesitation if problems occur. The Race Directors should anticipate and identify potential problems before they occur and make adjustments so they can quickly react. For example, if the waves are large, position lifeguards within the surf zone. If the weather is too warm, change the start to the cooler morning hours or the late afternoon. If jellyfish swarm, make sure to have plenty of household vinegar in spray bottles. In all cases, keep the athletes and spectators informed of potential hazards. Even if some athletes complain, the Race Director and staff must be prepared to take some verbal criticism in order to protect the safety of all.
WOWSA 4.17 – After the event is over, document the following in order to improve the race in the future: what went right and why, what went wrong and why, what went unexpected and how to prevent from reoccurring.
WOWSA 4.18 – The lead pack of athlete are usually well-attended to by the officials and volunteers. The attention of the race announcer and race officials are usually fixed on the leaders. However, the entire field demands the attention of the race director, on-the-water safety marshals and volunteers.
WOWSA 4.19 – Experienced water safety staff and Race Directors often divide the entire course into manageable segments. Each segment has a designated number of water safety personnel – both onshore and on the water – in order to take care of the entire field of swimmers. As the athletes pass from one segment to the other, the water safety staff should stay diligently focused on the athletes in their area – and are in close communication with others on the course.
WOWSA 4.20 – WOWSA highly recommends that all open water events should be captured on video. Not only is the effective cost of filming the race by hand-held video recorders relatively inexpensive, filming the race can serve the following functions:
WOWSA 5.1 – The start shall be pre-determined and noted in the event information. The start can be on land, on a fixed or floating platform, or partly or entirely in the water as long as all athletes have a fair opportunity to be in the position they wish. If there are crowded conditions at the start, the general principle of first come first serve applies. The Referee can give warnings and disqualifications before the start for cheating, non-adherence to the rules or pre-race instructions, or for unsportsmanlike conduct.
WOWSA 5.2 – When starting from a fixed platform athletes shall be assigned a position on the platform, as determined by random draw.
WOWSA 5.3 – Athletes may start anywhere within the starting area at their choice.
WOWSA 5.4 – Participants should be informed of the time before the start at suitable intervals. WOWSA recommends 10-minute, 5-minute, 3-minute and 1-minute intervals with a 10-second countdown unless the Referee and the Starter have determined a different system.
WOWSA 5.5 – The Referee and Starter shall attempt to execute a fair start, but safety shall be the overriding concern in crowded conditions.
WOWSA 5.6 – In the case that U.S. Masters Swimming or USA Swimming members are included in a WOWSA event, accommodations should be made as required under U.S. Masters Swimming rules. For example, U.S. Masters Swimming or USA Swimming members should start either 5 minutes before or after the non-U.S. Masters Swimming members or non-USA Swimming members as required by the rules of these respective governing bodies.
WOWSA 5.7 – A WOWSA-sanctioned event may start men and women, boys and girls, disabled and able-bodied athletes separately or together as it wishes. However, awards shall be given separately to each gender.
WOWSA 5.8 – The Starter shall be positioned so as to be clearly visible to all athletes.
WOWSA 5.9 – If, in the opinion of the Referee, an unfair advantage has been gained at the start, the offending athlete may be given a yellow or red flag .
WOWSA 5.10 – All escort and safety craft (e.g., kayaks, paddle boards, canoes, electric boats, motorized vessels) shall be stationed at a safe distance from the swimmers as determined by the local jurisdictions (e.g., Fire Department, Lifeguards, Coast Guard) at all times.
WOWSA 5.11 – The escort and safety craft shall not interfere with or impede any athlete. If an escort craft, intentionally or unintentionally, interferes with another athlete, the athlete who is guided by that escort craft shall be immediately disqualified.
WOWSA 5.12 – All escort safety craft shall navigate in such a way as not to maneuver through the field of athletes. Any violation shall lead to any immediate disqualification of their athlete and their immediate removal from the course.
WOWSA 5.13 – Although they may start together, in all other respects the men’s and women’s competitions shall be treated as separate events.
WOWSA 6.1 – The course shall be accurately measured by GPS or other appropriate means. The distance shall be measured using the shortest straight-line tangents between start, turn buoys and finish.
WOWSA 6.2 – Expected conditions and water temperatures shall be informed to the athletes in advance via the website and pre-race information.
WOWSA 6.3 – A certificate of suitability for use of the venue shall be issued by the appropriate local health and safety authorities. In general terms the certification must relate to water purity and to physical safety from other considerations.
WOWSA 6.4 – On the day of the event, the water temperature should be checked at least one hour before the start in the middle of the course at a depth of 40 cm.
WOWSA 6.5 – All turns, obstacles and landmarks of the course shall be clearly indicated to the athletes before the start.
WOWSA 6.6 – All starting platforms, feeding pontoons, turn buoys and guide buoys shall be securely fixed in position and not be subject to tidal, wind or other natural or unexpected movements.
WOWSA 6.7 – If possible, the final approach to the finish shall be clearly defined with markers or buoys of a distinctive color.
WOWSA 6.8 – The finish shall be clearly defined and marked.
WOWSA 6.9 – Athletes cannot be supported, touched or pushed during the swim at any point along the course as long as there is not a rescue or emergency. However, if the local rules allow, athletes may rest or place their hands and arms on their escort boat, stand-up paddleboard, kayak, paddle board, pier or other supportive structure during the event if they get sick, injured or are afraid of or get approached by marine life. Athletes who are touched, supported, pushed, dragged along, or carried by their escort kayak or paddle board at any point in the race shall not be eligible for awards.
WOWSA 6.10 – Athletes may be handed fuel (food) and hydration (drink) by their crew or coach from an escort boat, stand-up paddle board, kayak, or paddle board. The fuel and hydration may be provided hand-to-hand or via a feeding stick, water bottle on a rope or simply thrown to the athlete.
WOWSA 6.11 – Escort crew, coaches and the race organization shall endeavor to pick up all cups, gel packs and other discard items from the body of water. It is the goal of WOWSA-sanctioned events to leave the open water at least as pristine as it was before the event.
WOWSA 6.12 – The escort boat captains and crew, kayakers, stand-up paddle boarders or paddle boarders shall follow all instructions of the Referee and Safety Officer at all times. These individuals must have the safety of the all the athletes in mind at all times.
WOWSA 6.13 – The water temperature and conditions shall be documented by the Referee or Safety Officer.
WOWSA 6.14 – The race director must inform athletes of the expected conditions prior to the race day via the website and other race information. This will enable the athletes to prepare themselves to handle the expected water temperatures and conditions. If the water temperature and conditions fall outside this expected range on race day, the Referee and Safety Officer shall make this announcement and any modifications to the course as necessary.
WOWSA 6.15 – Properly rounding all Turn Buoys is the sole responsibility of the athlete. Athletes shall be asked to properly round the turns if they inadvertently miss a turn. If an athlete chooses to cut short the turn buoys even with a warning, he shall be immediately disqualified unless there are safety issues. If an athlete cuts short turn buoys due to safety issues, the Referee shall make a determination of a possible disqualification.
WOWSA 6.16 – In the case of an onshore finish, athletes are encouraged to clear the water and crawl, walk or run across the finish line under their own power. However, if an athlete is tired, weak, injured or is in obvious need of assistance, they should be immediately helped by volunteers. The top priority of all WOWSA-sanctioned races is safety and rules play a secondary role where there is risk of danger to an athlete.
WOWSA 7.1 – Athletes may swim any stroke style: any form of freestyle, breaststroke, backstroke, or butterfly or any combination thereof. Rules on butterfly, backstroke and breaststroke are noted in Sections 10.0, 11.0 and 12.0.
WOWSA 7.2 – Drafting behind and pacing along other swimmers is permitted (see exception in WOWSA 7.3). However, drafting behind escort boats, safety craft, kayaks and paddle boards is not allowed. Navigating parallel to watercraft is permitted.
WOWSA 7.3 – Drafting behind an escort boat on a solo marathon swim or relay, or on a solo channel swim or relay is not permitted. Swimming closely alongside an escort boat is permitted as long as safety of the athlete is maintained.
WOWSA 7.4 – Escort boat shall attempt to maintain a constant position so as to station the swimmer at, or forward of, the midpoint of the escort boat.
WOWSA 7.5 – Standing on the bottom during an event shall not disqualify an athlete but they may not walk or jump forward.
WOWSA 7.6 – Rendering assistance by an official or Referee to an athlete in apparent distress shall always supersede official rules of disqualification.
WOWSA 7.7 – Athletes shall be allowed to use skin lubrication or other such substances on the skin providing the substances are not serving to retain body heat. Lanolin, Vaseline®, grease, and other such substances are permitted.
WOWSA 7.8 – A pace swimmer is allowed but the athlete cannot draft off of a pace swimmer. Pace swimmers for disabled and blind swimmers can be in any position relative to the athlete.
WOWSA 7.9 – Coaching and the giving of instructions by the athlete’s representative on the feeding platform or in the escort boat is permitted.
WOWSA 7.10 – Feeding poles are not to exceed 5 meters in length when extended. No objects, rope or wire may hang off the end of feeding poles except flags. Athletes are permitted to retrieve water bottles attached to rope.
WOWSA 7.11 – Each escort boat or kayak shall display the athlete’s competition number so as to be easily seen from either side of the escort boat.
WOWSA 7.12 – Athletes may be disqualified by the Referee at any time. The Referee may give a warning, a Yellow Card (or Flag), or a Red Card (or Flag). Any number of warnings may be received by an athlete without consequence. Two Yellow Cards (or Flags) lead to an immediate disqualification. A Red Card (or Flag) leads to an immediate disqualification.
WOWSA 7.13 – If in the opinion of a Referee, an action of an athlete or an escort safety craft is an unsportsmanlike conduct, the Referee shall have the option to immediately disqualify the athlete. Unsportsmanlike conduct including pulling back an athlete by any body part, or sinking, dunking, punching, scratching, kicking, or swimming over another competitor.
WOWSA 7.14 – Escort and safety craft shall maneuver so as not to obstruct the direction or progress of any athlete.
WOWSA 7.15 – Escort craft shall attempt to maintain a constant position vis-à-vis their athlete, specifically the athlete is positioned near the mid-point of the escort craft on their primary breathing side.
WOWSA 7.16 – Standing on the bottom of a sandbar or ocean floor, and dolphining in and out of the water just after the start or near the finish, are permissible. Dolphining in the middle of the race is not allowed unless if this action is specifically exempted from this rule by the Referee.
WOWSA 7.17 – Athletes, if they encounter a shallow area along the course (e.g., within a coral reef, on a sandbar, along a jetty, or near a pier), may stand up if allowed by the Referee or Safety Officer for safety reasons. However, they may not walk along the course, dolphin or jump in the forward motion to gain an advantage.
WOWSA 7.18 – Rendering assistance to any athlete in apparent distress shall always supersede the rules of conduct and disqualification. If an athlete assists another athlete on a kayak, paddle board or on a boat while touching the boat, an official, a volunteer or another swimmer, this Good Samaritan athlete shall not be disqualified. When rendering assistance to another athlete during the race, the rules governing touching another individual, a fixed pontoon or water craft shall be waived.
WOWSA 7.19 – Rendering assistance to physically and intellectually disabled athletes is permitted.

A swimmer is allowed to stop swimming in shallow water as he approaches the shoreline and walk up on shore to clear the water as an athlete swimming freestyle would do. However, if the finish is in the water, a swimmer must touch the finish pontoon or pad with their hand while they remain on their back.
WOWSA 14.3 – The normal position on the back can include a roll movement of the body up to, but not including 90° from horizontal. The position of the head is not relevant.
WOWSA 14.4 – Kicking may be done in any fashion as long as the athlete remains on his back during the swim.

In order for a swim to be considered a Breaststroke Swim, the entire distance must be swum breaststroke as defined by the following rules:
WOWSA 15.2 – From the beginning of the first arm stroke after the start (either from shore or in the water) to the finish of the swim (either onshore or in the water), the body must be kept on the stomach to qualify as a Breaststroke Swim. While the athlete is swimming, he is not permitted to roll onto his back at any time or take any freestyle arm strokes or leg kicks, or do sidestroke of any type. A swimmer is allowed to stop swimming in shallow water as he approaches the shoreline and walk up on shore to clear the water as an athlete swimming freestyle would do. However, if the finish is in the water, a swimmer must simultaneously touch the finish pontoon or pad with two hands although they can be in a different plane.

There is no minimum distance of each stage. The total cumulative distance may be no less than 25 kilometers. The overall final distance is measured from the starting point to the finish in miles, nautical miles or kilometers. This is measured as the shortest straight line or shortest sum total of a series of lines and not the swimmers course.
WOWSA 16.2 – A stage swim, stage relay or stage race may also be a timed event. They may be more than one day and more than one stage may be swum per day.

During an assisted swim the following items may be used: neoprene suit or cap, fins, snorkels, scuba gear, shark cage, submersible drafting boom, jellyfish net, surfboard, hand paddles, neoprene cap, hand paddles, or anything else that may aid the swimmer with better floatation, propulsion, insulation, and lessen frontal resistance or drag. Swimming on the side of a boat to lessen wind, waves, or the current is also considered an assisted swim.
WOWSA 16.5 – Assisted swims do not qualify for any records for any body of water; however they will be given credit for the distance and a time. They are referred to as Assisted Swims. The item(s) used to assist the athlete must be identified and noted in the swimming log by the observer.
WOWSA 16.6 – If an obstacle, man-made or not, such as a dam, waterfall, locks or other is blocking the natural course of the direction of the swim or the athlete, it may be avoided. The athlete may exit safely before and re-enter after the obstacle. The distances avoided will be measured and subtracted from the total distance of the swim. The time will stop when the athlete exits and resume when the athlete starts. This obstacle safety exit will be noted in the Observer’s Report.
WOWSA 16.7 – During a stage relay, if an athlete drops out he may return at a later time. The team may continue without the Retired Swimmer.

If there are wetsuit and non-wetsuit divisions and one member wears a wetsuit, then the team will be designated as a wetsuit team. Only if a team has all non-wetsuit swimmers is the team designated as a non-wetsuit team.
WOWSA 19.1 – WOWSA open water swimming events encourage and support blind
swimmers to participate. Blind swimmers are allowed 3 general exceptions to the solo
swims performed by open water swimmers with sight:
(a) they can be tethered together in some fashion to another swimmer throughout
their swim for guidance,
(b) they can be led by swimmers who allow them to tap on their feet or other parts of
their body for guidance,
(c) they can be escorted by kayakers or paddlers or crew on an escort boat who
blow whistles for guidance (e.g., once for “go left” and twice for “go right”).
WOWSA 20.1 – Open water swimming events, their sponsors, participants, venues, suppliers and spectators increasingly wish to improve their sustainability and reduce their environmental impact. WOWSA events can take steps to minimize their plastic footprint.
WOWSA 20.2 – Swimmers, coaches, volunteers, officials, and support crew may not intentionally pollute any open body of water or its environs with trash or debris, including feed cups and gel packs, at any point before, during, or after the swim, from start to finish. Swimmers shall be disqualified if the swimmer or his crew members pollute the open water with cups, gel packs, bottles, trash, or other debris before, during, or after the competition or swim (solo or relay). It is the responsibility of the race director, staff, officials, and observers to monitor the behavior of the swimmers and their crew.
WOWSA 20.3 – WOWSA offers guidelines (see below), created by the Plastic Disclosure Project, to assist event organizers.
WOWSA 20.3.1 – Open water swimming events, their sponsors, participants, venues, suppliers and spectators increasingly wish to reduce their environmental impact. WOWSA events can take steps to minimize their plastic footprint. Plastic takes decades to fully degrade, can cause ecosystem and health impacts, and is often the cause of much of the waste that is found in racing environments.
WOWSA 20.3.2 – WOWSA offers guidelines [see below], created by the Plastic Disclosure Project, to assist event organizers. This lays out guidelines to assist event organizers, including a checklist to assist with planning and a scorecard to help evaluate progress towards certification as a PDP Sport event. These guidelines should be very achievable for most events from solo marathon swims to mass participation events. For events that already pride themselves on their sustainability, they should stretch further and seek ISO 20121 certification.
Overall sustainability of events is important, but these guidelines focus on minimizing an event’s ‘plastic footprint’. Plastic is a useful and valuable resource, especially to sports event organizers. However, plastic needs to be managed properly, and doing so can be an easy, but significant, step towards a more sustainable event. Plastic is often highly visible to event participants and those that use the location afterwards, so brands and events want to be careful about the image they leave behind, and also demonstrate that they are responsible and effective event organizers and supporters. In addition, plastic is a valuable commodity, and there are often strong economic reasons for ensuring it is not wasted. Furthermore, plastic takes decades to fully degrade, can cause ecosystem and health impacts, and is often the cause of much of the waste that is found in our racing and training environments, both on land, and in the water. This is completely avoidable, and athletes are a perfect segment of society that can be ambassadors in driving a large-scale reduction in plastic waste.
Checklist and Tips
To help move towards zero and minimize an event’s ‘plastic footprint’, event organizers should consider the following as develop and review their plans:
Have you made a commitment to reduce, reuse, and recycle all plastics?
Have you considered all the situations where plastic is provided?
Can plastic items be replaced or substituted with something more sustainable?
Where plastic is provided, can favorable plastics be chosen?
Where plastic waste is generated, is it collected in an organized way?
What assistance can you anticipate from local waste management and recycling services?
Where recycling is conducted, are you confident in the recycling process?
WOWSA/PDP Sport Scorecard – Moving Towards Zero Plastic Footprint
To help gauge your progress towards a minimal plastic footprint being left behind after your event, measure your event against this scorecard. For each question, score your event appropriately, and total your response. In general, if you either have no plastic, or manage plastic very carefully to minimize both reputational and environmental impacts, your event will score sufficient points to become a certified PDP Sport event.
0 – Your event has made a commitment to reduce, reuse, and recycle all plastic waste and publicized it to all staff, volunteers and participants
3 – Your event has made a commitment to reduce, reuse, and recycle all plastic waste, with no publication to staff, volunteers and participants
5 – Your event has not made a commitment to reduce, reuse, and recycle all plastic waste

If you would like to be certified, and use the PDP Sport logo in your event material, website, etc., please contact the Plastic Disclosure Project and the World Open Water Swimming Association to self-register, along with your scorecard as per the items above.
If you have any questions about these guideline or the Ocean Recovery Alliance’s Plastic Disclosure Project, contact Doug Woodring ([email protected]), Andrew Russell ([email protected]), or Richard Herstone ([email protected]).
Plastic Disclosure Project
The focus of Ocean Recovery Alliance, in partnership with WOWSA, is to bring together new ways of thinking, technologies, creativity and collaborations in order to introduce innovative projects and initiatives that will help improve the ocean and open water environment. Plastic Disclosure Project is part of the United Nations Environment Programme’s Global Partnership on Marine Litter.
Plastic Disclosure Project is similar to that of carbon disclosure, whereby companies, organizations and events annually report their plastic use or waste accumulation. By having metrics for measurement, it is easier to then manage the use of plastic in a more efficient manner, with our communities, and the environment, as the benefactors. Five main ways of improving plastic’s use include less waste in the supply chain, more recycling within the business operations, more recycled content in the material, new design, and the use of new materials.
ISO 20121:2012 specifies requirements for an event sustainability management system for any type of event or event-related activity, and provides guidance on conforming to those requirements. The London 2012 Olympic and Paralympic Games was the catalyst behind the development of ISO 20121, which provides the framework for identifying the potentially negative social, economic and environmental impacts of events by removing or reducing them, and capitalizing on more positive impacts through improved planning and processes.
WOWSA 21.1 – Contiguous Solo Crossing Relays are swimming events where a number of athletes completes consecutive point-to-point solo swims or circumnavigations of any duration, length or type in an open body of water and where each swimmer starts after being touched by the previous swimmer who has cleared the water. Each swim by the individual swimmers is called a Leg of the Contiguous Solo Crossing Relay. Each swimmer must start and finish on land. Each swimmer is referred to in numerical order. That is, Swimmer #1 is the first swimmer to begin the Contiguous Solo Crossing Relay, Swimmer #2 is the next swimmer to swim after the first Leg is completed, Swimmer #3 follows until the last swimmer completes the final Leg.
WOWSA 21.2 – The number of athletes in a Contiguous Solo Crossing Relay must be at least two, but can number as many as desired. The venue can be an ocean, sea, lake, river, channel, canal, fjord, lagoon, estuary, bay, reservoir, dam, lido, rowing basin or any man-made or natural body of water. The athletes must follow the traditional rules that govern their chosen body of water or competition if there is a recognized body that oversees swims in the area (e.g., Channel Swimming Federation or Catalina Channel & Swimming Federation).
WOWSA 21.3 – For a point-to-point Contiguous Solo Crossing Relay to be recognized, each athlete must cross body of water, touch the intended terrestrial finish point, clear the water under their own power and then immediately touch the next swimmer to begin the next Leg. For a circumnavigation of an island or Contiguous Solo Perimeter Swim around the perimeter of a lake, each athlete must completely swim around the course, touch the intended terrestrial finish point, clear the water under his/her own power and then immediately touch the next swimmer to begin the next Leg.
WOWSA 21.4 – For Ice Swims, WOWSA follows the rules and procedures of the International Ice Swimming Association.
WOWSA 21.5 – In Elimination Sprints, the top 50% of the finishers of each heat will advance to the second round. The second round will begin five minutes following the initial swim and the top 50% of those swimmers will advance to round three. This process will continue until there are less than twenty swimmers in the final round. In this round, swimmers will be allowed to start by diving from the starting boat to allow maximal speed.
WOWSA 21.6 – In an open water medley swim, the athlete shall cover the four standard swimming strokes in the following order: butterfly, backstroke, breaststroke and freestyle. Each of the strokes must cover one quarter of the total distance.
WOWSA supports and accepts the Rules of Marathon Swimming as defined by the Marathon Swimmers Federation for those swimmers who wish to follow its guidelines in ungoverned swims.
However, the rules, guidelines and traditions of existing and future governing bodies are respected by WOWSA. That is, the MSF Rules do not supersede or replace the rules of the Channel Swimming Association, Channel Swimming & Piloting Federation, Catalina Channel Swimming Federation, Farallon Islands Swimming Association, British Long Distance Swimming Association, Irish Long Distance Swimming Association, Lake Tahoe Swimming Society, International Ice Swimming Association, International Winter Swimming Association, Lake Erie Open Water Swimming Association, Santa Barbara Channel Swimming Association, Vancouver Open Water Swimming Association, Northeast Kingdom Open Water Swimming Association, Japan International Open Water Swimming Association, Tsugaru Channel Swimming Association, Menorca Channel Swimming Association, Association of Korea Open Water Swimming, Universal Marathon Cold Swimming Association, Lake Ontario Swim Team, Solo Swims of Ontario, Dubai Open Water Swimming Association, Great Lakes Open Water Swimming Association, Massachusetts Open Water Swimming Association, Asociacion de cruce a nado del Estrecho de Gibraltar, FINA (Fédération Internationale du Natation Amateur), Tsugaru Strait Swimming Association, Hawaiian Channel Swim Association, Kaiwai Channel Association, and other local governing bodies.
The Marathon Swimmers Federation (MSF) Rules of Marathon Swimming are a set of standards and guidelines for undertaking a solo, unassisted open-water marathon swim in any body of water.
MSF Rules may be used by any swimmer who wishes to attempt a swim for which there is no local governing body. They also may be used by local governing bodies wishing to adopt a global standard — or as a foundation upon which to establish local exceptions.
MSF Rules do not override local rules — they aim to codify their shared spirit.
The Spirit of Marathon Swimming
MSF Rules are guided by the traditions and spirit of unassisted marathon swimming.
Marathon swimmers embrace the challenge of crossing wild, open bodies of water with minimal assistance beyond their own innate physical strength and mental fortitude. There are ways to make the sport easier, but marathon swimmers consciously eschew them.
Marathon swimmers take pride that their achievements can be meaningfully compared to the achievements of previous generations, because the standard equipment of the sport has not changed significantly since 1875.
Marathon Swim: A nonstop open-water swim, undertaken according to standardized rules, and requiring at least several hours of sustained effort to complete. Ten kilometers without significant assistance from currents is the minimum distance considered to be a marathon swim.
Nonstop: Remaining in the water for the entire duration of the swim from start to finish without intentional physical contact with escort vessels, support personnel, or other objects (fixed or floating).
Unassisted: Without artificial assistance to performance, other than the standard equipment of the sport. Any swim using nonstandard performance-enhancing equipment, or otherwise violating the rules of unassisted marathon swimming, is considered an Assisted Swim.
Standard Equipment of Marathon Swimming
The swimmer does not need to declare the use of standard equipment (i.e., it is assumed).
Any equipment not specifically listed here is considered nonstandard equipment. Use of nonstandard equipment must always be declared, even if the equipment’s benefit to performance is ambiguous.
Examples of nonstandard performance-enhancing equipment:
Swims using nonstandard, performance-enhancing equipment cannot be considered unassisted. Examples include:
Equipment that may retain or increase warmth – e.g., wetsuits, neoprene caps, booties, gloves.
Equipment that may increase speed – e.g., flippers, paddles, shark cages.
Equipment that may increase buoyancy – e.g., pull buoys, wetsuits.
Auditory pacing aids – e.g., music players, metronomes.
Electronic devices attached to the swimmer, which transmit information to the swimmer – e.g., wristwatches, navigation aids, biofeedback monitors.
Performance-enhancing drugs on the World Anti-Doping Agency List of Prohibited Substances.
The swim observer documents the facts of a swim and verifies the swim’s adherence to the declared rules. Documentation produced by a qualified observer is the single most important source material for authenticating a swim claim.
The primary qualifications of an observer are:
The observer must be capable of dispassionately evaluating the swim and its adherence to the declared rules. If the observer is acquainted with the swimmer, (s)he must be able to separate the personal relationship from his/her duties to observe, document, and verify.
The observer must be knowledgeable about the rules, traditions, and spirit of marathon swimming, and with the responsibilities of observing a marathon swim.
The MSF maintains a global network of qualified, willing observers. Local observer networks and official trainings are offered by following organizations:
Observers who have not attended an official training may also demonstrate expertise through their personal history in the sport – as a swimmer, crew-member, or administrator.
Very Long Swims
If a single observer is not able to maintain alertness for the entire duration of the swim, an additional observer is necessary. The MSF recommends two observers for swims anticipated to last longer than 18 hours, and three observers for swims anticipated to last longer than 30 hours. Overnight swims in the 10-18 hour range may also require a second observer.
On swims with multiple observers, a lead observer should be designated to coordinate the observer team and documentation procedures.
High-Profile or Unprecedented Swims
Swims of unusual magnitude or notoriety – especially unprecedented swims – demand a stricter standard for observer qualifications and reputation. In such cases, it is essential that the observers are trusted by the broader community of marathon swimmers.
The MSF recommends a minimum of two highly qualified, reputable observers for high-profile swims, to reinforce their credibility.
“Golden Rules” of Marathon Swimming
Transparency of Swim Conduct
The intended conduct of the swim – including Swim Rules and any nonstandard equipment to be used – must be communicated fully and clearly before the swim begins, to everyone involved in the swim attempt, and in all public promotion. The declared rules and equipment may not be changed once the swim has begun.
Independent and knowledgeable observers must document the facts of the swim and verify the swimmer’s adherence to the Swim Rules.
This section defines standard MSF Swim Rules for a one-way solo swim (Point A to Point B). Standard rules for multi-leg swims, circumnavigation swims, relay swims, and stage swims are defined in the MSF Rules Supplement.
Individual swimmers or local governing bodies may adopt MSF Swim Rules in full, as shorthand for “standard conduct.” Or, they may adapt the rules to local circumstances, as long as two conditions are met:
The declared Swim Rules must be read aloud by the observer in the presence of the swimmer and all support personnel before the swim begins.
Start & Finish
The swim begins when the swimmer enters the water from a natural shore. If geographic obstacles (e.g., cliffs) prevent the swimmer from clearing the water at the start, the swimmer may begin the swim by touching and releasing from part of the natural shore (e.g., cliff face).
The swim finishes when the swimmer clears the water on a natural shore, beyond which there is no navigable water. If geographic obstacles prevent the swimmer from clearing the water at the finish, the swimmer may finish by touching part of the natural shore.
The swimmer may not make intentional supportive contact with any vessel, object, or support personnel at any time during the swim.
The swimmer may wear a single textile swimsuit with standard coverage, one latex or silicone cap, goggles, ear plugs, nose clips, and may grease the body. The swimmer may not use any additional equipment that benefits speed, buoyancy, endurance, or heat retention.
The swimmer may not intentionally draft behind any escort vessel or support swimmer. The swimmer may swim alongside an escort vessel, but may not intentionally position him or herself inside the vessel’s bow and displacement waves, except while feeding.
A support swimmer (or swimmers) may accompany the solo swimmer for a limited duration. Multiple support swims are allowed, but should not occur consecutively. The MSF recommends a maximum of one hour per support swim and a minimum of one hour between support swims.
The support swimmer may not intentionally touch the solo swimmer and must position him or herself at least slightly behind the solo swimmer.
Authority on the Escort Vessel
The observer is responsible for documenting the facts of the swim, interpreting the swim rules, and keeping the official time.
The pilot of the escort vessel (or lead pilot, if there are multiple vessels) is the ultimate authority in all other matters. (S)he may cancel the swim at any time, for any reason. The pilot is responsible for following all relevant local maritime regulations.
Responsible Environmental Stewardship
Everyone involved in the swim attempt – swimmer, observer, support personnel, and escort boat personnel – must treat the environment respectfully and prevent avoidable harm to marine wildlife and ecosystems.
Continuance of the Spirit of Marathon Swimming
If any issue regarding swim conduct arises that the Swim Rules do not clearly address, the swimmer should act – and the observer should judge – in accordance with the spirit of unassisted marathon swimming.

Special Swim Types
Certain types of swims require additions or modifications to the standard rules for a one-way swim (Point A to Point B). Swimmers and observers should incorporate the indented portions below into their declared Swim Rules, as appropriate.
A multi-leg swim is a swim that reaches one or more intermediate destinations (shores) before the final destination.
The simplest form of a multi-leg swim is a two-way (“double”) channel crossing – a swim from one shore to a different, non-contiguous shore, and then returning to the first shore.
However, a multi-leg swim need not return to the original shore. For example, a swim from Island A to Island B to Island C is also a multi-leg swim, with Island A to Island B as “Leg 1” and Island B to Island C as “Leg 2.”
For a multi-leg swim, add the following two rules:
1. After finishing one leg of the swim, the swimmer may rest for up to 10 minutes before beginning the next leg. While resting, the swimmer may be supported by a natural land mass but not by people or artificial objects.
2. Timing of the first leg begins when the swimmer enters the water and ends when the swimmer finishes the leg. Timing of subsequent legs begins at the end of the previous leg and includes any break on shore.
A circumnavigation swim is a swim around an island (or islands). For a circumnavigation swim, replace the standard Rule #1 (Start & Finish) with the following:
The swim begins when the swimmer enters the water from the island’s shore. If no beach is available on the island, the swimmer may begin the swim by touching and releasing from part of the island’s shore (e.g., cliff face).
The swim finishes when the swimmer swims around the island and then clears the water beyond the starting point (or touches the island’s shore beyond the starting point, if no beach is available).
If access to the island is restricted, the swimmer may start and finish offshore, as long as (s)he “closes the loop” by swimming beyond the starting point, as measured by GPS.
A swim undertaken by a team of two or more swimmers, swimming in successive turns of a fixed time interval, in a fixed order.
For a relay swim, add the following two rules:
A stage swim consists of two or more “stages,” between which the swimmer rests on shore or on an escort vessel.
For a stage swim, add the following two rules:
Each stage after the first should begin at or behind the finish location of the previous stage.
If the resting location is in open water, the observer must record the GPS coordinates of the stage start and finish locations.
Local Rule Variations in Marathon Swimming
Rules in marathon swimming date to 1927, when the newly-formed Channel Swimming Association wrote its first regulations for English Channel swims. CSA rules (often known as “Channel Rules”) are the basis for most contemporary marathon swimming rules and standards.
Local adaptations of Channel Rules have produced many slight variations on the original. In the absence of a global governing body with global rules, this has sometimes produced confusion about which rules are truly fundamental, and which are open to local modification.
Interestingly, even the “original” Channel Rules are written as local guidelines, not global guidelines. For example, CSA Rules state that after finishing the first leg of a two-way crossing, “Walking 200m along the shoreline to Cap Gris Nez is not permissible.”
The MSF believes there is a fundamental “spirit” shared by the many variations on Channel Rules, and it aims to codify this global spirit while remaining flexible to local adaptations. The MSF also recognizes existing well-established local marathon swimming rules as legitimate adaptations of the global spirit of the sport.
MSF Rules do not invalidate existing local adaptations. Nor should existing local variations necessarily be applied globally.
WOWSA incorporates the USA Triathlon recommendations on use of wetsuits in open water swims.
