They couldn't find any manufacturers to supply new boats, so it became run your own.
Not sure about how that will impact the gualification regattas to get into the Alter Cup however.
Let's say you win the qualifier on your F18, and the AC is on a Hobie 16...but Who's Hobie 16? Or will they be supplied?
Or will it from now on always be a 'BYOB" event?
