You can sail just about any production spin boat in this race.
As long as it's 18-22 feet long.
This is a fast freekin race. The first two legs are 100 plus miles. I think the record is 5.5 hours for the first leg (105 miles). Leg one is (as Chris Green puts it) pure sailing euphoria. It's like a hundred mile run from "A" mark to "C" mark. It can be a bit tactical too and not just a follow the leader race.
One year, we averaged 25 knots on leg three (60 miles). It's a fun and challenging race. I wish someone would show up with a Tornado sometime.
