Board at the stern from the wide swim platform. The transom door is on centerline. The cockpit is large, fully enclosed with a canvas / isinglass enclosure (2012), and has fitted carpeting on the sole. A wide sliding door provides access to the salon, with its open floor plan.

A bookshelf and entertainment cabinet is to port. The L-shaped galley has solid surface countertops and a new Force 10 three burner propane range (2012). The helm station is starboard, with a sliding helm station door providing exit to the side deck with protective bulwarks. A pantry for storage is beneath the helm station sole -- lots of storage volume.

The forward companionway provides access to the master cabin with its island berth (new custom SlumberEase mattress) and a good amount of storage. The guest stateroom has two twin beds and storage. The head is accessed from the companionway or the master stateroom and is roomy and well-lit. The enclosed shower is large and customized with attractive tile.

Broker's Comments

This Mainship 390 Trawler appears as a nearly new boat. She has been exceptionally-well maintained, has been customized, decorated and updated by attentive owners, and is immediately ready to cruise. Lots of newer features -- canvas and isinglass enclosures, dinghy davit system, inverter, stove, generator / watermaker and electronics among them.

The sedan-style design of this two-stateroom flybridge trawler provides a very open and large-feeling interior while still affording a big cockpit and wide, safe side decks for ease of operation. This would be a comfortable and easy boat to operate and cruise. A large enclosed flybridge with plenty of seating adds to the enjoyment.
