The guy who just surveyed my Allmand, mentioned that he thought it was a 312 series. I never heard of this but that doesn't surprise me, I never heard of a Allmand sailboat 6 months ago either. Has anyone ever heard of this model? Also I heard from a knowledgeble sailmaker that Allmand 31s have two differant mast heights. Anyone? Also looking to decipher my hull number. Anyone have the code?
