Most of the Anglo-American boat folklores about boats built oversized so they can survive everything is just cruiser conspiracy to prop up the market.I was surprised how quickly it broke up also. Westsail 42s have a lot of glass in them.
I think that's a bit harsh. They go pretty well with 20kts+ of wind and track well enough to be easy on autopilots. Crossed the Pacific with a few in 2017 that we kept pace with but then I was on another boat you probably don't like, a Crealock 37.Perhaps overly stout for a boat, but not for a seawall. Represents a useless compromise: too heavy to sail, too light to survive.
