Only THREE challengers have signed up. What a joke! Designing and building foiling boats is far too expensive. Go back to traditional monohull displacement sailing. Cheaper, more challengers and better racing.
That would be dumb. I thought proper sail boats were boats that used a sail and the wind as opposed to a motor and diesel? Hence the sport and hobby - Sailing.
Therefore, how many hulls your sail boat has should be irrelevant.
