Ron, hehehehehe. The Coast guard requires that all hand's space be clearly marked with (if I remember right) 4 inch red letters stating their function on board. Last time we got boarded I wrote "deck hand" backwards on my fore head. They didn't think it was funny. (but it really was! lololo) ship got wrote up and I got fired. Happened a lot back in the day.
Ron, Not only will your cabin have room for your pontoon, (maybe below?) but will be adorned with a brass stamped thing on your door stating you are in fact the "head and executive engineer in charge"
