Mainship 390 Power Yachts For Sale

Listed examples of the Mainship 390 illustrate a pilothouse trawler layout designed for extended cruising and liveaboard comfort. One listing describes a 2003, 39′ Mainship 390 (Yinzer) noted as a Great Loop veteran; a second listing (Donary) provides a detailed walkthrough of the interior and deck arrangements common to the model.

Access from the waterline is via a fiberglass swim platform and transom gate leading onto a hardtop-covered aft deck. From the aft deck owners can access side decks, ascend molded-in steps to the flybridge, or enter the salon through a sliding aluminum-and-glass door. The salon is fitted with a sleeper sofa and a custom hi‑lo teak table to starboard, entertainment and storage cabinetry to port aft, and a port‑forward galley. Engine room access is through sole hatches in the salon.

Accommodations are arranged with a forward master stateroom featuring an island queen berth and direct access to an ensuite head with an enclosed shower. A guest stateroom to port offers side‑by‑side single berths with storage beneath, while the companionway provides access to a second head with enclosed shower. Reported interior headroom measures include 6’4″ in the salon, 6’3″ in the master, 6’4″ in the guest stateroom and 6’7″ in the shower; berth lengths and specific portlight/hatch arrangements are also indicated in the listings.

The lower helm is located starboard forward in the salon and includes navigation and engine controls plus a side deck access door. The flybridge is described with a custom hardtop, overhead lighting, enclosure, bench seating with storage, helm seating, fold‑up tables and engine and anchor controls. Deck features noted in the listings include a non‑skid finish, aluminum railwork, lazarette and generator access below the aft deck, and fold‑down steps on each side of the transom.
