Mainship 390 Trawler

The Mainship 390 Trawler represents the perfect balance of classic nautical design and modern cruising performance. Designed with the coastal cruiser in mind, this single-diesel, fuel-efficient trawler offers the comfort, livability, and range typically found on much larger vessels — all in a manageable, user-friendly package.

Built on a semi-displacement hull, the 390 delivers stable and economical cruising at displacement speeds, yet offers enough power to get you there faster when needed. The full-keel design provides directional stability and added protection for the running gear, making her ideal for long-range coastal adventures or extended stays aboard.

Above deck, "Kuleana" features wide side decks with secure handholds, molded-in steps to the bridge, and a spacious flybridge with centerline helm, full instrumentation, generous seating, and excellent visibility in all directions. The upper deck also boasts an aft boat deck with davit, ideal for dinghy storage or entertaining with a view.

Below, the salon is bright and inviting, thanks to large windows and warm cherry wood finishes. A lower helm station offers protected cruising options, while the open-concept layout provides ample space for relaxing or entertaining. The galley is fully equipped with a refrigerator/freezer, stove, oven, microwave, and deep stainless-steel sink, plus plenty of storage for extended cruising.

The private master stateroom features a centerline queen berth and dual hanging lockers, while the guest stateroom offers twin berths and flexibility for family or crew. A spacious head with a separate stall shower completes the accommodations.

Whether you're planning on living aboard, coastal hopping, or simply enjoying weekends on the water, the Mainship 390 Trawler delivers classic trawler style, rugged construction, and practical design in a cruiser that's as comfortable as it is capable.
