2004 Mainship 400 Trawler

This 2004 Mainship 400 Trawler is a 36-foot twin-engine diesel trawler built on a fiberglass semi-displacement hull. Twin Yanmar 4LHA-STP 240 hp diesels power the boat, with 3,090 hours on the engines. The design is known for its stable handling and 360-degree visibility, with a spacious flybridge suited to extended cruising.

Below decks, the accommodations include a galley with two Isotherm refrigerators and a microwave, plus a head with a separate shower stall and Vacuflush toilet. The flybridge features reupholstered seating, a full canvas top, and Isenglass enclosure panels for all-weather use.

Recent upgrades include a rebuilt Kohler generator, fresh bottom paint completed in February 2026, new Garmin GPS units at both upper and lower helm stations, and Raymarine autopilot for passage making. The boat is outfitted with a solar panel and controller, plus a Xantrex inverter/charger for off-grid power management.

The boat sustained minor dock rash near the bow pulpit and starboard aft rub rail that has been professionally repaired.
