You have to be careful with Gulfstars. For a good portion of the company's history, they built motorsailers (and they weren't particularly good at either motoring or sailing). They also are known for quality issues such as blistering during this time period. There is a fairly narrow time span where they built really nice, good-performing, quality sailboats, and that is approximately from 1975-1981 (again, approx... I am not an expert on Gulfstar, I am just repeating what the listing broker of my boat told me, and he used to work for Gulfstar). I couldn't be happier with my boat. It has an awesome interior, it is very sturdy, and it is really fast. Just make sure you do your research so you don't get one of the "bad" boats (which may not be bad for your purposes, just make sure you know what you're getting).
