WM, prior to purchasing SEA LEVEL, I spent 5 days, and several hundred miles on a KK 42...observations, PRO: fit, finish, quality was good, comfortable interior layout, pilothouse very good, nice aft cockpit, all in all nice boat. CONs: many arrrgh single engine, dislike silhouette and angle of bow deck, flybridge configuration-chopped up, in any seaway more than 2' you better be stablized, nearly tossed out of PH--desk lamp wasn't so lucky. The above boat had bow thruster--an absolute must w/single engine. My thoughts, going away was, lose your engine, bow thruster and your in a bathtub. The owner NEVER used the FB. As for Mainships, absolutely not the quality of GB or KK, but bang for your buck, tons of them for sale in Southwest Fl. PS, went aboard a 46 Gb motoryacht-1985--for sale, Ft. Myers, told it will go for $150Kish, alot of boat, with what appeared to have good bones...tho very dirty...not associated with sale. Good luck.
