Tim,
My slip neighbor has a Prairie 47, I know this is a bit larger than you are looking at- but I gotta admit the CPMY is a great improvement over a sundeck. We own a 42' sundeck and I would not trade it for anything because of the features you mentioned. But Larry enjoys all of the outside living space like we do, along with convenient landing space the small CP adds. We get on the old girl from the side at our current berth, but getting down to the dink is always a climb, and I am afraid it won't get any easier as we get older. I'm not sure how large you have to get to get the cockpit. Might search Yachtworld for all trawler CPMY
