The Mainship 400 Trawler offers an overall great layout with two helm stations, two private staterooms and a spacious head with separate stall shower. There is a bright and airy salon with a convertible settee and dinette table for four and fully equipped galley. The large upper flybridge has plenty of room for seating 10+ persons. Entertaining is easy with the summer kitchen option on this boat that provides a propane grill, sink and icemaker aft of the centerline helm. Wide, molded steps offer safe and secure footing to the aft cockpit. The cockpit features a hardtop for sun/weather protection. Going forward, there are wide, lighted and recessed walkways with overhead protection leading to the foredeck.
