Description

Power Boat Guide: "A huge success, the Mainship 350 Trawler is an economical low maintenance coastal cruiser with classic trawler lines and a good turn of speed. Considered a "performance trawler" the Mainship rides on a semi-displaced hull capable of higher speeds than full displaced trawlers. Stepping inside from the covered aft deck, large wraparound windows provide lots of natural light in the saloon and excellent visibility from the lower helm". Slow Ya Roll features comfortable seating for a couple to starboard in the salon and a L-shaped galley with refrigerator/freezer, Corian counters forward and entertainment/storage aft to port. A teak and holly is attractive and functional, and a sliding door at the lower helm provides easy access to the deck. There are two staterooms with a queen island berth forward (6'4" headroom) with two lockers, drawers under the berth and a double guest berth. The head features 6'4" headroom and a separate shower. The molded in steps provide easy bridge deck/flybridge access from the aft cockpit. The flybridge will be the likely choice for entertaining which features plentiful seating, dinning and expansive views with large canvas coverage for weather protection. The upper helm provides four conner visibility, electronics for navigation and with both bow and stern thrusters the boat is easily handed in tight quarters. Lastly, powered by a single Caterpillar 3116 300 HP diesel engine, she has the power to reach 14 knots and is most efficient at 8 knots. Slow Ya Roll will tick the box for many Great Loop enthusiast, coastal cruiser, and those who enjoy entertaining in comfort.
