any mass-manufactured older trimarans available?

[miamibeach]

Hi,<br />I am looking to purchase a 40-50ft trimaran sailboat, fiberglass, and I have not had much luck in finding such an animal....I appreciate the roominess, and ultimate relative stability of such a vessel, as I plan to do some near-coastal chartering with one......if I can find one. I don't want, nor can afford, a new cat or tri, so I am hoping someone has some information on any manufacturer of older, super-solid fiberglass tri's out there. The comparison (in terms of construction), would be the very sturdy monohull gulfstar 51's and 45's of around the 1975 era........anyone out there with an answer???...or one for sale?....please give me an e-mail...many thanks
