Oh yeah, they sure do. I grew up sailing on leaners and I crew regularly on a Melges 24, and PHRF sucked then as much then as it does now. The best and worst thing about PHRF is the numbers are set regionaly which creates all kinds of problems. Makes for some interesting gossip and email threads though.

Monohull sailors and multihull sailors IMHO are the same people with the same interests, it's just the platform we do it on is a little different. And yes, they have the same OD vs. PHRF (open) debate that we do.
