Cruise in comfort and style

Trawler owners today are on a mission. They are looking for boats that set up for cruising the Great Circle Route, navigating to Alaska and puttering through the British Isles. To be sure, this requires a sea worthy boat, but it also requires a comfortable salon for living and entertaining. It mandates staterooms and heads that are built for cruising families and couples, not for glitz at a boat show. Many Asian trawler builders shoehorn a lot of living space in a salon, Pilot House and forward stateroom(s). The problem is that you are climbing or going down steep stairs from sunrise to sunset and at the end of the day you are exhausted. That is why we have the salon on one level and the staterooms just two steps down – we build cruising boats, not jogging trails.

The salon has a two person helm chair and comfortable L shaped settee to stbd. The settee converts to a sleeper sofa (no need to purchase an optional pull out unit). On the port side are two leather recliners and a 26″ flat panel TV (tied into the Bose Stereo sound system). Open the two aft salon doors, breathe in the fresh air and wind down after a long day’s run or entertain – you can do both on the Expedition Trawler. The galley is conveniently located on the same level, port side forward for ease in serving a party or for just the two of you.

Retire to a queen size bed (with innerspring mattress) in the master stateroom. Warm cherry wood lockers with cedar lined interiors sized to meet you needs are what you expect and what Mainship gives you. There is no need to climb up into a high perched bed just to get some sleep. Lighting, a deck hatch with screen and shade, storage and a large molded fiberglass head are what you expect and get for a boat built for the mission. The guest stateroom has twin beds and has been used as an additional locker, full time sewing room or even a bedroom.

Mainship is known for its easy access through the transom door, wide deck walkways for ease in handling the lines and the first company to use stairs instead of ladders to get to the bridge. The bridge is the largest in its class, seats eight in comfort and offers a Summer Kitchen on the aft deck of the flybridge. Many of our owners cook their evening meals there and enjoy watching the sun go do day after day.Economy of operation and speed are also a hall mark of Mainship. With single electronic engine options of 380 and 440 horsepower or twin 260’s, you can loaf along at 7 knots, make some serious mileage at 13 -15 knots with the singles or run to 17 plus knots with the twins. You choose. The bow thruster is standard with the single engine and more and more of our customers are adding the stern thruster also. Make your departures and arrivals fun and easy for all.

Despite the level of practical luxury and quality built into the Expedition, it continues to be extremely affordable compared to other trawlers in its class, says Krueger. “We are able to take advantage of volume buying for our production materials through the Luhrs Marine Group, plus incorporate the efficiencies of production and computer-aided building processes.” Mainship Corporation, America’s Trawler Builder, is an employee-ownership company, and part of the Luhrs Marine Group. It is one of the largest independent boat builders in the world. Mainship also has the distinction of celebrating its 30th Anniversary this year as the largest volume trawler builder in the world. Superior value and quality cruising boats from 31’ to 45’, built to meet the needs of the people who own them are the reason Mainship is number one.
