The first tuber will start in the inner tube on their stomach or their back. At the 25M mark the tuber must touch the wall with any part of the body, NOT with the inner tube. Then proceed back to the other end of the pool. If the tuber falls out of the inner tube during the course the tuber must get back in the inner tube without forward progress. The second tuber starting out may have the help of the other team tubers.
Same thing goes for the third tuber.
Only the tuber in the inner tube may make forward progress at anytime. A tuber may NOT have any push off from other team tubers. Each tuber is allowed only to tube one leg in any relay event. The tuber will have finished the race or his leg, when any part of his body touches the end wall. False starts will follow the rules previously stated.
