Description
This Mainship 390 Trawler is a well-appointed and comfortable motor yacht designed for effortless coastal cruising and extended stays aboard. She features a spacious flybridge with bimini top, an open sundeck, and a beautifully finished teak interior with a roomy salon, full galley, and two private staterooms.
The flybridge is expansive and open, offering excellent 360° visibility. A forward centerline helm is complemented by a captain’s chair and guest seating to port and starboard. Aft, the open sundeck provides ample space to relax and enjoy the ride. A starboard-side stairway leads down to a covered cockpit with transom door and swim platform, while sliding glass doors offer easy access into the salon. Fresh bottom paint and striking blue hull accents enhance her overall appearance.
Inside, the salon is bright and inviting with large windows, generous headroom, and a teak and holly sole. A large convertible sofa and a lower helm station are located to starboard, while the port-side galley features solid-surface countertops, stainless steel sink, refrigerator, electric range, microwave oven, and abundant storage with both upper and lower cabinetry.
Below deck are two comfortable staterooms. The guest stateroom offers twin berths with custom mattresses, under-berth storage, and a hanging locker. The head includes a vanity and a separate shower stall. The master stateroom features a queen berth with custom mattress and cover, dresser, hanging locker, and overhead hatch for natural light and ventilation.
Power comes from very rare and highly desirable twin 240-hp Yanmar diesel engines. The vessel is equipped with dual HVAC systems for year-round comfort and a generator for reliable offshore electrical power. Deck hardware includes stainless steel bow rail and pulpit, radar mast, wide side decks, and a swim platform for easy water access.
This 2003 Mainship 390 Trawler stands out as a well-maintained, thoughtfully upgraded cruiser that’s turnkey and ready for cruising, offering an exceptional blend of comfort, reliability, and value.
