The Mainship 400Trawler is an updated version of the very popular Mainship 350/390 Trawler.  The design is beautifully simple with ease of use clearly in mind. 

Built on a semi-displacement hull with a full keel the single-engine version offers excellent propeller protection.  She also offers trawler economy with the ability to make 16 knots plus when desired.

With wide sidewalks, molded bridge steps, a large aft cockpit covered by an equally large aft deck, upper and lower helm stations and no exterior teak the boat is a natural and easy traveler.

The layout is equally easy to use, the entry via the swim platform to the cockpit and into the Salon are all on a single level.  There is a wide transom door and double-opening French style doors that open from the Cockpit to the Salon.  The Salon features a double reclining settee to port with a booth dinette forward.  The Galley is to starboard with the lower helm just ahead, the lower helm has a convenient access door to the starboard walkway.

The staterooms are forward and down three steps, the master located in the forward cabin features an Island berth with a privacy entrance to the head compartment.  The guest stateroom is to port, opposite the head compartment. Here is a single berth and excellent storage.  NOTE, the original design has two single berths in the guest stateroom, here one has been removed for additional storage.

The head compartment features a Vacu-Flush head, a large shower stall, a privacy entrance to the master and a day entrance from the hallway.
