2003 Mainship 400 Trawler

2003 Mainship 400 Trawler — Loop-Proven, Meticulously Updated, Turn-Key

Few boats in this class come to market this well sorted. This Mainship 400 has just completed America's Great Loop under her current owners, and six years of continuous, documented investment — most of it in the last thirty-six months — is all still aboard.

At her heart is a single Caterpillar 3126TA, 385 horsepower, with just 1,375 hours. The 1,000-hour service is long behind her, heat exchangers flushed, impellers and zincs current, and a three-stage Racor setup with fuel polishing lets you change filters underway without breaking stride. Fresh Pettit Trinidad bottom paint and a polished, waxed hull, May 2025.

The electronics are genuinely current: Raymarine Axiom+ displays at both helms — 12" above, 9" below — with Quantum radar, EV-1 autopilot, Tri-Data instruments, Class B AIS, and Standard Horizon DSC radios at both stations. Mast-mounted Starlink Gen 3 runs off its own 12-volt supply.

Belowdecks she's a proper two-stateroom cruiser: island queen forward with en-suite head and separate glass-door shower, twin-berth guest cabin to port, 6'6" headroom throughout. Headliners and wall coverings — the Achilles heel of many Mainships of this vintage — have all been replaced with upgraded LED lighting, and teak-and-holly-look soles replace the original carpet. The rebuilt propane range with working oven and an engine-heated hot water system mean you can cook and shower at anchor without running the generator.

Topside, a ¾ flybridge enclosure (2024) extends the season, and the aft bridge deck carries a summer kitchen with grill, sink, and ice maker. Seawise davits handle the included Avon 310 RIB and Honda 15hp. Side Power bow thruster with new gear leg and quiet props (2025), Kohler 8kW generator, Mastervolt 2000W inverter/charger (2025), Trojan AGMs, reverse-cycle heat and air, Sea-Fire suppression, and a hinged mast that drops in two minutes for the 17' air draft the Loop demands.

With a 3'8" draft and 300 gallons of fuel, she's ready for the Bahamas, the Chesapeake, or another lap of the Loop. Ground tackle, spares, fenders, linens, and galley kit all convey. Step aboard, provision, and go.
