I'm pretty sure Northwest Explorations in Bellingham still has at least 1 42MY in their charter fleet. I have to disagree a little bit with Ray; at least on the 49MY we once chartered in SW FL, you still had walk around capability (something we really perfer too), you just went up a step or two. The MY also wipes out the cockpit (an issue for many) and so the MSR gains that space too. The MSR on the 49MY was quite noticeably bigger than on the 49 Classic we used to charter in the PNW, and it picked up a day head too. I have not cruised a 42 classic and MY, but have been aboard each and other than the day head, have the same observation.
