Mainship 390 Trawler

Best for

• Couples wanting apartment-like cruising space
• Great Loop and coastal cruising where dimensions fit
• Owners valuing molded stairs and a large flybridge

Trade-offs

• Wide beam and high air draft restrict marinas and waterways
• Modified-V hull is not a traditional full-displacement trawler
• Single-engine examples depend heavily on thrusters or handling skill
• Large deck and superstructure areas require careful moisture inspection

Known concerns

• No model-specific concern has been promoted to B-Atlas’s evidence threshold. This does not mean the model has no age-, condition- or hull-specific risks.

Inspection focus

• Confirm whether propulsion is single or twin and verify engine-room access
• Inspect deck, flybridge and window structures for moisture intrusion
• Inspect fuel tanks, exhaust, steering and thruster installations
• Verify actual air draft and mast-lowering arrangements

About this record

B-Atlas preserves uncertainty: missing information remains unknown rather than being treated as a negative. Specifications and guidance describe the model record; individual boats can differ by year, equipment, refit and condition.
