Total distance is 50 meters. Pairs of 2 men, 2 ladies and mixed couples take part in OCTOPUS 50 m. At the starting point athletes must be ready on the right and left sides from pool curbstones. One athlete must wear scuba, another one should use mask, snorkel and fins. NOTE: in mixed couples the team can decide who will wear scuba – man or lady. After start divers enter to the water by giant step. Scuba diver (next donor) descends and swims underwater.
The finswimmer (next acceptor) swims underwater with the breath hold. At the segment 1-15 m from the border donor must supply acceptor with alternate air source (octopus). Acceptor must start breathing from octopus and keep a stable physical contact with donor, avoiding octopus loss. If athletes start air sharing later than 15 m the penalty is 10 seconds. They finish the distance when they reach opposite border (50 m). Finish is registered when the scuba diver touches the border with his hand. Maximum length of octopus hose is 110 cm.
