You will have an early start time from your pilot, where you will gather with your crew and meet your allocated Observer – wrap up warmly on the boat, as your starting point is about 10 minutes away. The pilot and Observer will tell you where your starting point (according to the rules) is. A stop watch will be started as soon as you leave the starting point. Then it is up to you to swim! Your pilot will return you to the starting point on completion of your attempt.
