A fully loaded Valiant 42 won Class C in the Swiftsure Race this year. So don't be sure a boat can't be a blue water cruiser and a race boat. It just takes skilled sailing and a good rating.
NIGHT RUNNER, a 42' cruiser of my design that has been around Cape Horn won Class B. Another example of a boat that is both an offshore cruiser and a race boat.
Class A was won by ICON another of my designs. I'm still feeling smug.
