2005 Mainship 400 Trawler

The 2005 Mainship 400 is a 40-foot fiberglass trawler built around a single Yanmar diesel engine producing 370 horsepower. The design emphasizes fuel-efficient cruising and long-range capability, combining traditional trawler lines with a wide 14-foot beam that opens up the interior spaces. The boat carries a bright, open salon lined with large windows, a fully equipped galley with solid surface countertops and full-size appliances, and substantial storage throughout.

The accommodation plan includes two staterooms and one head. The forward master features an island queen berth, while the guest cabin offers twin berths. Both staterooms provide generous headroom and storage.

Outdoor areas include a spacious aft cockpit suited for entertaining, wide side decks for safe movement around the boat, and a flybridge with full helm controls, seating, and excellent sightlines. The flybridge layout supports both cruising operations and relaxed time on the water.
