Mainship DC40 Nantucket Trawler Twin Crusader 350 Gas engines. The following was taken from a review of the vessel. It points out most of the features better than I can. Double-cabin cruisers have long been a staple in the marine marketplace, and the affordably priced Mainship 40 DC was notable in the late 1980s for her distinctive, trawler-style profile. This is a very practical boat, long on useful features. Despite her traditional Downeast profile, her performance and interior accommodations are similar to those of a modern motor yacht. The salon dimensions are about average for a 40-footer with plenty of room to entertain guests in comfort, if not luxury. A lower helm, port and starboard salon deck doors, and a built-in bar were standard. The full-width aft stateroom includes a double berth, excellent storage, and a tub/shower in the adjoining head compartment. (In 1985, light oak woodwork replaced the original dark teak interior joinery.) Topside, the aft deck is large enough for casual entertaining, and it’s notable that a factory hard- top was never available. Additional features include a bow pulpit, wide side decks, fold-down radar mast, and a swim platform. The Mainship 40 DC will cruise at a respectable 18 knots with standard 350hp Crusader gas engines (mid 20s top).
