Depends a LOT on which Gulfstar
you get. The 50 and various other Lazarra designs are indeed of the quality you mention. The Hirsh designed 45 is an entirely different animal, not designed at Gulfstar. It is a beefed up boat as compared to the others, intended for hull
stiffness and speed. If my boat is any indication of how they built them, the sure are solid. They did have bilstering problems in the 70's, but I have a 1987 that I have almost no complaints about. I have been living aboard
full time for closing in on two years now.
Please PM me for specific questions, unless everyone would like to hear me go on about the Gulfstar in public.
It's a great boat. It's a perfect compromise (in my mind) between speed and offshore
ability. It has drawbacks (damn hull
liner), but is constructed exceedingly well.
