Neill was nominated for the 2012 World Open Water Swimming Woman of the Year award. Her World Open Water Swimming Association award reads, Look at Tina Neill and nothing hints at records. Talk to Tina Neill and nothing she says hints of greatness. But the introverted, humble explorer of the raw potential of the human spirit has been making waves in the open water throughout her career. In her own quiet way, Neill loudly proved once again how uniquely special she is. She hit the lumpy water at night, battled the elements far from shore, and finished the next night, completing an unprecedented 28 hour 41 minute crossing of the 52-mile (83.6 km) San Clemente Channel. Like her record-setting backstroke swims in the England and Catalina Channels, she efficiently funneled her talents and enthralled her crew with her strength, stamina and speed. For her quiet nature despite swims that scream volumes, for always remaining under the radar despite record-setting exploits, for the pure genius of her aquatic talents, Tina Neill is a worthy nominee for the 2012 WOWSA Open Water Swimming Woman of the Year.
