There is no better value in a Mainship 400.  The Mainship 400 Trawler was introduced in 2003 as the successor to the very popular 390 Trawler and the manufacturer included a larger salon allowing for more galley space and a dinette. Mechanical access was improved with a larger engine room and much better access to the lazarette, where the generator is located. The hallmark feature of the 400 has to be the summer kitchen at the aft end of the flybridge this twin Yanmar Diesel engines @240HP was custom made by Mainship for a very knowledgeable boater and featured upgrades and systems not typically found on any other 400 Trawler.

Manufacturer Description

There is plenty of room for seating and relaxing on the bridge. There is even a Summer Kitchen option providing a grill, sink and icemaker aft of the centerline helm. Wide molded steps offer safe and secure footing to the covered aft deck. Going forward, there are wide, lighted and recessed walkways with overhead protection leading to the foredeck. A stainless steel Sampson post and dual roller pulpit is perfect for setting the anchor and the optional windlass makes retrieval a snap. All rails, hatches and port lights are now fashioned from 316L stainless steel for easy maintenance and great looks. All Mainships, including the 40, are featuring beautiful cherry wood interiors. All cabinets, drawers and tables are solid cherry and the optional cherry and holly sole is very traditional as well as serviceable. The extended salon includes an Ultra leather sofa, entertainment center with Bose audio system, and Luce flat screen TV. A starboard side galley offers a full size, dual voltage refrigerator and freezer, microwave, 3-burner range and oven, and even a coffee maker. Special attention has been given to general and dishware storage and the location for an under counter trash receptacle. To port of the lower station is a full dinette that seats four with a comfortable bench and two chairs. Forward, is a master stateroom with a centerline inner spring queen berth and plenty of hanging, drawer and locker storage. A second stateroom offers two single berths and an optional innovative desk arrangement, and the head, with a separate stall shower is accessible from the master stateroom or the companionway.

The aft end of the area is open and features the very popular summer kitchen option with sink and ice maker. There is also a mounted 24" round table and a folding radar mast which color matches the gel coat. Moving forward into the covered area of the bridge, there is an L-shaped settee on port and straight settee on starboard with a folding table between. At the forward end of the area, the helm is on centerline with a pedestal seat and additional forward facing seats on either side.

Aft Deck / Cockpit

One of the great features of the 400's cockpit is the fiberglass top which is the aft end of the bridge deck above. The top provides sun and rain protection and gives the cockpit the feeling of back porch. Other features include a transom storage locker with washdown, a transom door for easy access to the swim platform, molded in stairs to the bridge, a large lazarette access hatch and easy access to the bow via wide side decks with high bulwarks. What is not as noticeable is that there is a second custom molded-in generator access hatch just outside the salon doors which allows direct access to the top of the generator. No other 400 Mainship has this feature!

Electronics & Helm

Simrad electronics were chosen for "Carousel" because of their superior performance and quality. In order to install the electronics package, a number of factory modifications had to be made to the boat. The most visible change was the custom lower helm, which allows all the electronics to be flush mounted. In addition, the radar mast was over-sized, extended and reconfigured in order the hold the 4kw open radar antenna and the sending unit for the wind speed and direction indicator. The electronics installation is to a very high standard with only the finest components used.
