Manufacturer Provided Description

The Mainship 390 Trawler blends today's technology with years of experience in crafting thousands of trawlers. Inside the spacious cabin, for example, is a lower helm station that's complete with full instrumentation and a windshield equipped with wipers and washers. The salon features warm teak highlighted by designer fabrics, a color television and VCR, a stereo, and opening windows with screens. Deck access is made easy for shorthanded cruising with a starboard helm sliding door. There is also a large screened sliding door to the cockpit. The 390 Trawler's galley is equipped for cruising or entertaining with a range, an oven, a microwave, a full-size refrigerator, an oversize sink, abundant cabinets and Corian countertops. The large master stateroom has a center island bed, cedar-lined hanging lockers, an opening portlight and hatch, and again more storage. For guests, a second stateroom features twin berths along with a hanging locker, storage, an opening hatch and a portlight. And finally, the easy cleaning, molded fiberglass head offers a built-in vanity, a shower, an electric marine toilet, an opening hatch, a portlight and a mirror. The power to travel is provided by a standard single diesel or optional twins. Both include freshwater cooling, an engine alarm system and a standard fire extinguisher system. To make docking easier, a bow thruster is standard on single engine boats and optional on boats with twin powerplants. On the flybridge there is a large area for entertaining or lounging, seating for more than six, and a drop-leaf table. The center helm has great visibility, full instrumentation and plenty of room for electronics (note the radar mast). This deck is reached by a wide, molded stairway with a full handrail. Access forward to the anchor is protected by a high bulwark and a walk-around deck. In the cockpit there is more than ample storage with deep wells and a lazarette.
