The Mainship 350 Trawler (called the Mainship 390 in 1999 2005) is a stylish, moderately priced coastal cruiser with classic trawler lines and a good turn of speed. Unlike a true trawler with a full-displacement hull, the 350/390 is built on a faster modified-V hull with flat aftersections and a shallow, full-length keel. She’s a very roomy boat inside thanks to her wide 14-foot, 2-inch beam, and the floorplan manages to in clude double berths in both staterooms as well as a separate stall shower in the head. (Note that the guest stateroom is partially tucked beneath the galley.) Visibility from the lower helm is excellent, and a deck door provides easy access to the foredeck. Aft, a sliding glass door opens to the covered cockpit where a series of molded steps (instead of a ladder) ascends to the extended flybridge. Additional features include deep, well-protected side decks, an integral swim platform, transom door, a full teak interior, and radar mast. Among several engine choices, a single 300hp Cat diesel will cruise the Mainship 350/390 at 10–12 knots (about 14 knots top)
