Stephen, We purchased a 44 MC back in July and have hull number 114 out of the 115 that appear to have been made. 1980 was the last year for the MC. There are actually quite a number of differences between the MC and MY, that came out in 1981. The MC was built on the Gulfstar 44 ft sailboat hull and is a full displacement-hull. Ours has the twin Perkins turbo diesel engines T6.354 series. The 44MY is a semi-displacement planing hull. The layout is similar, but the MY has a combined engine room/gen room that is accessible via a stair well. The MC has separate hatches inside the cabin for access to the two work areas. Your best bet is to go on-line and look for some 44 MY boats that are for sale and compare photos/videos. My wife and I actually like the layout and wood work in the 44 MC better than the 44 MY. Hope you are enjoying your boat. I would be glad to share experiences, etc. Carleton
