The Mainship 400 Trawler (called the 41 Expedition in 2009; 414
Trawler in 2010–12) is an updated version of the company’s popular
350/390 Trawler, with the extra length used to enlarge the main deck
salon. She rides on the same semi-displacement hull as her
predecessor, with flat after-sections and a shallow, full-length keel.
The expansive two-stateroom interior of the Mainship 400 is
arranged with an island berth in the master stateroom and single
berths in the mid-stateroom, which is partially tucked under the
salon sole. A dinette—something the 390 sorely lacked—seats four,
and the large galley is equipped with a built-in microwave,
flat-screen TV, and Corian counters. In the cockpit, the straight,
molded stair steps to the bridge are an improvement over the 390’s
For many, the spacious flybridge of the Mainship 400—with its
Jenn-Air grill, dinette table, and wet bar—is among the highlights
of the boat.
Additional features include a washer/dryer, a convenient deck
access door at the lower helm, covered cockpit, wide side decks, and
high-gloss cherrywood interior joinery.
This model has upgraded Twin 240 hp Yanmars…cruise
efficiently at 12 knots and reach top speed of 15-16 knots.
