Our Thoughts

The 2001 Mainship 390 Trawler represents a proven, well-maintained platform for extended cruising and coastal exploration. With a modified vee hull, solid fiberglass construction, and a displacement-oriented design, this 39.75-foot trawler delivers the efficiency and seaworthiness that define the class.

Hull, Deck & Structure

The hull features a solid fiberglass layup with a glass-and-cored sandwich construction above the waterline, finished in white gelcoat. The vessel rides on a full fiberglass walk-around deck system with aluminum rails and high bulwarks—a practical design that minimizes maintenance compared to traditional brightwork. A wide fiberglass swim platform with a centerline transom door provides easy water access and tender deployment via the Weaver davits. The divided anchor lockers and moulded stairway to the flybridge are well-conceived for a vessel of this size and purpose. Three deck hatches support natural ventilation throughout the accommodations.

Propulsion & Performance

A single Cummins 330 horsepower, six-cylinder diesel engine (Serial #46051340) powers the 390 Trawler. The engine shows approximately 5,080 hours on the meter and has been recently serviced with a new raw water pump, coolant pump, starter, heat exchanger, and all new hoses, plus a complete valve adjustment and after-cooler cleaning. The Twin Disc transmission received an oil change at 3,600 hours. A dripless shaft seal, 1¾-inch stainless steel shaft, and four-bladed 26-inch propeller complete the running gear. At 1,600 RPM, the vessel cruises efficiently at 7 knots consuming approximately 3 gallons per hour; maximum speed reaches 15.5 knots at 2,800 RPM. This powerplant is the preferred single-engine configuration for Mainship 390 owners seeking low-maintenance, economical long-distance cruising. Engine oil and zincs are changed annually, with the most recent oil service completed at 4,853 hours including antifreeze and coolant.

Fuel, Water & Systems

Tankage includes 300 gallons of fuel in two 150-gallon aluminum tanks, 120 gallons of fresh water in two poly tanks, and a 35-gallon holding tank under the forward cabin steps equipped with a 2025 12-volt macerator. A 6-gallon hot water heater supports the head and galley. The Racor fuel filter with vacuum gauge provides engine protection. A rebuilt hydraulic steering system and recently installed 2025 aft bilge pump, along with four 12-volt bilge pumps, ensure redundancy in critical systems. The Lewmar dual-action 12-volt windlass with flybridge remote and foredeck controls simplifies anchor handling.

Electrical & Power Generation

The electrical system operates on 12-volt DC and 110-volt AC circuits. A Kohler Advanced Control 8-kilowatt generator (Serial #0676355) with approximately 900 hours provides onboard power generation. Two 2025 lead-acid 8D batteries with a combiner switch serve the main house systems, while a separate lead-acid battery powers the generator. A Promariner 50-amp battery charger and a 2025 separate generator battery charger ensure reliable charging capability. Two-zone air conditioning with reverse-cycle heat provides climate control. The cabin features 12-volt LED lighting

2001 Mainship 390 Trawler for Sale – Classic Cruising Yacht with Flybridge and Single Diesel Engine
Overview
The 2001 Mainship 390 Trawler represents a proven design in the cruising trawler category, purpose-built for comfortable long-distance voyaging and Great Loop cruising. At 39.75 feet in length with a 14.17-foot beam and 3.67-foot draft, this vessel combines traditional trawler styling with practical modern systems. The single Cummins 330 horsepower diesel engine, recently serviced with comprehensive mechanical updates, delivers efficient cruising at 7 knots consuming approximately 3 gallons per hour at 1600 RPM, while capable of 15.5 knots at 2800 RPM when needed. With approximately 5,080 hours on the engine meter and a documented history of annual maintenance, this Mainship has been operated by an owner-engineer who prioritized system integrity and proper upkeep. Located in South Bristol, Maine, the vessel is priced at $134,500 and represents the type of capable, well-maintained platform that appeals to serious cruising buyers seeking a modest-footprint trawler with established reliability.
Hull Design and Deck Configuration
The Mainship 390 features a modified vee hull with keel, a design that balances seaworthiness with the shallow-draft characteristics valued in cruising waters. The solid fiberglass hull employs a glass and cored sandwich construction above the waterline, enhancing structural integrity while reducing weight. The white gelcoat finish is complemented by white fiberglass walk-around decks featuring aluminum railings and high bulwarks that provide security and weather protection during passage-making. Deck layout emphasizes safety and accessibility. A centerline transom door and very wide fiberglass swim platform facilitate boarding and water activities, while divided anchor lockers forward provide dedicated storage for ground tackle. The moulded staircase with stainless steel rail connects the cockpit to the flybridge , creating a logical traffic pattern between helm stations. Three deck hatches support interior ventilation and natural light, while the Lewmar dual-action 12-volt windlass with flybridge remote control and foredeck up-and-down controls simplifies anchoring operations. The absence of outside brightwork reduces maintenance demands—a practical advantage for owners who cruise extensively and prefer to focus on mechanical systems rather than cosmetic varnish schedules.
Engine and Propulsion System
The single Cummins 330 horsepower six-cylinder diesel engine is the heart of this trawler's efficiency profile. This engine model, paired with a Twin Disc transmission, is recognized for reliability and fuel economy in the cruising trawler segment. At 5,080 hours, the engine shows well and has benefited from recent comprehensive mechanical service including a new raw water pump, new coolant pump, new starter, heat exchanger service, all-hose replacement, valve adjustment, aftercooler removal and cleaning, and rebuilt hydraulic steering. Propulsion components support extended cruising. The 1.75-inch stainless steel shaft drives a four-bladed 26-inch right-hand propeller. A dripless shaft seal eliminates the traditional stuffing box, reducing maintenance and eliminating drips in the bilge. The Racor fuel filtration system with vacuum gauge provides protection against water and particulate contamination. Transmission oil was changed at 3,600 hours, and engine oil, antifreeze, and coolant were last serviced at 4,853 hours. Annual zinc replacement and regular oil changes document ongoing preventive maintenance discipline. Cruising performance at 1,600 RPM yields approximately 7 knots and 3 gallons per hour—an efficiency metric that extends range and reduces operational costs on extended voyages. Maximum speed capability reaches 15.5 knots at 2,800 RPM when conditions warrant faster transit.
Fuel, Water, and Holding Systems
Tankage supports extended cruising. The fuel system comprises two 150-gallon aluminum tanks totaling 300 gallons, providing substantial range at economical cruising speeds. The 120-gallon water capacity is divided between two poly tanks, ensuring redundancy and flexible water management. A 35-gallon holding tank located under the forward cabin steps is equipped with a new 12-volt macerator installed in 2025, enabling convenient pump-out at marine facilities. A 6-gallon hot water heater rounds out the freshwater system, supporting comfortable galley and head operations.
Electrical System and Power Generation
The electrical infrastructure balances 12-volt DC and 110-volt AC circuits through dedicated panel systems. A Kohler Advanced Control 8-kilowatt 8E0Z generator with approximately 900 hours provides shore-independent power generation, supporting air conditioning, refrigeration, cooking, and comfort systems during anchorages. The generator is conveniently located under the cockpit sole for easy access and service. Battery capacity consists of two 2025 lead acid 8D batteries with a combiner switch for combined or isolated operation, plus a separate generator battery. A Promariner 50-amp battery charger manages charging from shore power, while a new separate charger for the generator battery ensures proper charging of that dedicated system. Two 30-amp shore power cords support connection at marina facilities. Electrical distribution includes 12-volt LED lighting throughout the cabin, four 12-volt bilge pumps for redundant water removal, and a new 2025 aft bilge pump installed for enhanced bilge management. Two-zone air conditioning with reverse-cycle heat provides temperature control in both cabin and salon areas. A 2025-replaced Vacuflush pump supports the freshwater head system. Underwater lights, though present, are not operational.
Helm Station and Navigation Electronics
The lower helm position to starboard is the primary control station, featuring a side door for easy access and a practical layout for solo or two-person operation. The helm console integrates multiple navigation and communication systems through Raymarine and Garmin platforms, supported by a Morse control shifter and throttle for engine management. Primary navigation electronics include a Raymarine E90 Radar, GPS, and Fishfinder/Depth sounder with touch-screen interface, providing integrated situational awareness for passage-making and anchoring. A Raymarine ST70 autopilot reduces helm fatigue during extended transits, supporting single-handed cruising capability. A 2025 ICOM IC-M330 VHF radio with a rebuilt Raytheon scanner ensures reliable communication on marine frequencies. The Raymarine GPS antenna was recently replaced, supporting accurate positioning. Two Aquameter 4-inch compasses provide magnetic reference and redundancy. A small Garmin ECO-Map DV on the flybridge offers supplemental navigation capability at the upper helm. A Shakespeare television antenna supports air reception for entertainment during anchorages.
Flybridge and Upper Helm
The flybridge represents a signature feature of the Mainship 390 design, accessible via circular stairs with stainless steel rail from the cockpit. The space is fully instrumented and equipped for command-level operation. A stainless steel steering wheel, Bennett trim tab switches, Morse control shifter and throttle, and Rule Aquameter compass support boat handling. An ICOM VHF radio and Raymarine ST70 autopilot repeat primary navigation functions, enabling independent operation from the upper station. A Garmin GPS ECO-Map DV provides supplemental charting capability. Comfort and entertainment systems enhance extended time on the flybridge. A Fusion stereo with speakers and Bluetooth connectivity supports music streaming and entertainment. A Plexiglass Venturi windscreen provides weather protection, while a 2020 full enclosure in dark green canvas with a canvas extension over the aft end transforms the space into a weather-protected outdoor salon. Port and starboard bench seating accommodates six, while a double-wide helm seat provides comfortable seating for two at the controls. A folding centerline table, two folding chairs, and a small wooden table support dining and socializing. A Sidepower bow thruster with joystick control enhances maneuverability in tight anchorages and marina approaches. The windlass remote control is accessible from the flybridge, allowing anchor handling from the upper station.
Accommodations and Interior Layout
The interior is appointed in attractive varnished wood finishes, supporting a warm, traditional aesthetic. The vessel accommodates four in two staterooms, with a generous head featuring a separate shower and fresh water Vacuflush toilet. The master stateroom forward features an island queen berth with cedar-lined lockers and hanging storage, plus drawers under the mattress for efficient use of space. An overhead hatch provides natural light and ventilation. The guest cabin aft to port contains a double berth (converted from twin bunks to queen configuration), with a hanging
