This Mainship 400 Expedition was originally designed with two separate single berths in the second stateroom. The owners preferred to have more storage and hanging space. There is still a single berth on the port side. The space is also used as a dressing area including a full length mirror.

The master stateroom has a centerline queen berth with easy access on both port and starboard sides. There are hanging lockers on both sides . There are also storage drawers under the berth. The master berth has a custom innerspring mattress with custom bedding and pillow top.

The salon dinette converts to a double berth and there are two large full length seats on the flybridge that are very comfortable sleepers.

The flybridge has seating for eight plus an aft bridge deck area with sink, BBQ and Ice maker. There is plenty of room for four deck chairs and an installed table. The chairs are included. The fully enclosed bimini top has a great feature. Instead of un-zipping the large clear plastic sections to create ventilation each section has separate U-shaped zip outs that are easy to open and close. The enclosed bridge is large with the plus of the aft deck section being open for summer sun. Total LOA 41’4″.
