adjective, noun - An unassisted swim is an attempt or completion of an open water swim undertaken according to standardized rules. An unassisted marathon swim requires a swim of at least 10 kilometers without significant assistance from currents.
Unassisted swims are done without aid of a shark cage, jellyfish cage, fins, snorkel, paddles, wetsuit or other protective swimwear or gear in order to minimize or eliminate one or more obstacles (e.g., shark attack, jellyfish stings, cold water, or distance). In an unassisted swim, a swimmer wears only traditional swimwear without neoprene (as defined by the English Channel swimming community), goggles, and if desired, ear plugs, and one swim cap. In either an Assisted or Unassisted swim, a swimmer can swim together with a Pace swimmer.
Unassisted Marathon Swim
An Unassisted Marathon Swim is defined by the Marathon Swimmers Federation as a swim without artificial assistance to performance, other than the standard equipment of the sport. Any swim that benefits from assistance - in the form of nonstandard performance-enhancing equipment, supportive contact with the swimmer, or other violation of the spirit of unassisted marathon swimming - is considered an Assisted Swim.
