The 2001 Mainship 390 is a 39-foot fiberglass trawler powered by a single Caterpillar 3126 diesel engine rated at 300 horsepower. Built on a modified-V hull with a protective keel, the boat draws 3 feet 9 inches and has an air draft of 16 feet. The single-engine configuration balances fuel economy with low maintenance compared to twin setups. The engine has logged 3,402 hours and features fresh water cooling, dual Racor fuel filters, and an integrated alarm system. A factory bow thruster and aftermarket stern thruster aid maneuvering, while custom hinged engine compartment hatches allow easy access for routine checks.
The layout below deck centers on a forward master stateroom with a queen walk-around island bed, cedar-lined hanging lockers, and abundant storage. A portside guest cabin offers twin berths with dedicated hanging space and storage drawers. The head includes a molded fiberglass design with vanity, electric marine toilet, and a separate shower stall. The salon features wood flooring, teak joinery, and two recliner chairs replacing the original factory couch. The galley is fitted with Corian countertops, a NovaKool refrigerator and freezer, a Princess electric three-burner stove with oven, GE microwave, and a Raritan ice maker.
Navigation and helm stations span upper and lower positions. The upper station includes a Raymarine Axiom touchscreen plotter and integrated autopilot; the lower helm has a Garmin GPSMAP 740s plotter, windshield wipers, and a starboard sliding door. Both stations carry magnetic compasses. Additional electronics include a depth sounder, VHF radio, and a rear-facing docking camera. Entertainment consists of a Fusion marine stereo with flybridge control and a secondary interior Bluetooth system, plus a Vizio Smart TV in the salon.
The expansive flybridge offers full 360-degree visibility from the center helm, a folding drop-leaf table, and lounge seating. Recent upgrades completed in spring 2025 include a new premium Bimini top with full Strataglass enclosure, freshly applied anti-fouling bottom paint, and heavy-duty transom dinghy davits. Ground tackle was upgraded to a Lewmar 33-pound anchor with 110 feet of 5/8-inch chain and 100 feet of nylon rode. Deck features include wide molded fiberglass stairs to the flybridge with full handrails, deep walk-around side decks with high bulwarks, and a protected aft cockpit with large screened sliding door and deep storage wells.
