A round the island powerboat challenge, with a small but crucial difference - to be the fastest and most efficient petrol boat.

A challenge to bring your boat to Alderney and compete against all shapes and sizes. The waters around the English Channel's third largest island are notorious, with a twist to make things even more interesting - each boat will have it's fuel tank (or topup quantity) weighed at the end of the challenge.

There are three prizes: The bronze award for completing the course in the fastest time, silver for doing it with the most amount of fuel remaining and the big trophy for maximum points based on both speed and fuel efficiency.

There is already a great deal of interest in the challenge which is planned for the spring bank holiday 2010, each competitor will need to have their plan submitted and demonstrate and understanding of Alderney's dramatic tides, exposed sea conditions and treacherous rocks before being entered into the competition.
