Brief Summary

If you have been thinking about moving up into the cruising life but are not sure if you (or your spouse) will like it, then the new Mainship 35 might be just the ticket for you. Don’t think that just because this boat is only 35’ long you can’t do long-distance coastal work in her. You can. Remember that the now much-revered Grand Banks line of trawlers started with a 36-footer. Forty years ago that boat started out a couple of generations of yachtsmen, many of whom ended up becoming blue water veterans. The new Mainship 35 is affordable ($315k MSRP), easy to handle (has both a bow and stern thruster standard), and is equipped with dependable diesel engines, either twins or a single, for economical operation.

    Mainship 35 Trawler (2010-) Line Drawing


    Captain's Report

    Mainship 35 Trawler
    The Mainship 35 is an ideal way to put one’s toes in the water of the cruising lifestyle without a large financial outlay. Imagine this boat with a navy blue hull.

    No matter how small a boat you own now, moving up to a 35-footer is not such a big jump. The Mainship 35 weighs just 20,000 lbs. (9,091 kgs.), has a 14’2” (4.36 m) beam and has both an upper and lower helm, with hydraulic steering and electronic throttles and shifts as standard. We think this is an ideal way for many older couples who are empty nesters to finally get started on that life-long dream without a lot of financial exposure. Likewise, it is also a good boat for a young couple with small kids to get started on if you know your destiny is one of those beautiful 65’ or 70-footers in 20 years or so. Think of this boat as your summer cottage, but one that is moveable from place to place, and you never have to pay extra for waterfront real estate (nor the taxes!)

    Mainship 35 Trawler
    Mainship helps the dream come true for many boaters.

    The Back Story

    During the 1930s Henry Luhrs stared a small boat yard in New Jersey called the Luhrs Sea Skiff Company. After the war the company grew and in the 1950s his sons John and Warren became involved with the business. At one point the company was producing over 1200 boats a year. In 1965, Bangor Punta, a huge timber conglomerate that was buying up several boat companies and other businesses in recreation at the time, made Henry an offer too good to refuse and the company was sold. The brothers, John and Warren, soon struck out on their own and formed Silverton Marine Corporation, the first of the Luhrs Marine Group of companies.

    Sail and Power

    Under the guidance of their father, the brothers were very successful. Warren, being an accomplished sailor knew they could adapt their building philosophy to sailboats and Hunter Marine was incorporated in 1973. Hunter is now known as the largest sailboat builder in North America. The international fuel-crisis in the ‘70s gave a huge wake-up call to boat builders, and John and Warren saw opportunity in building an economical, single diesel cruising boat that a family could afford. Mainship Corporation was formed in 1977 and soon outgrew the existing facilities. A new plant was built in Marlboro, NJ and was home to Mainship until 1992 when it was moved to St. Augustine, FL. A couple of years ago it moved back to New Jersey.

    Mainship 35 Trawler
    The Mainship 35 can make a good turn of speed but this is not efficient cruising in a boat that is supposed to be a trawler.

    Over 1200 of the traditionally-styled cruisers were built before Mainship began building a European-inspired line of cruisers in 1988. The new boat line did well for several years, but Mainship’s real destiny was to return to the trawlers that made them famous. In 1994, the first new Trawler, a 35 sedan, was introduced. Today, the Luhrs Marine Group builds about 20 different models in three brands: Mainship, Silverton and Luhrs. The company has always believed in building low and mid price-point boats and today it is hard to find a serious power boater over 60 years old on the north Atlantic east coast of the U.S. who hasn’t at one time or another owned a Luhrs product.

    It All Starts with Value

    Having built price-point boats for decades, Luhrs has broken the code on how to do it and still compete with their far more expensive competition in terms of performance, handling and livability. The new Mainship 35 is a good example of just that.First, this boat has a 14’2” beam (4.36 m) which the company says is widest in its class. That is a beam/length ration of 40% which is nearly unheard of in powerboats over 24’. We think that ample beam is a good thing in this type boat because it allows a lot of living space in the main salon, below, and up on the flying bridge, too. This boat is not about speed, nor is she intended to compete with Italian motoryachts. Rather, her mission in life is to be a reliable, comfortable, North American trawler-type coastal cruiser that is affordable to a wide swath of the American boating public. Just as price is important, the 35’s beam is also a large part of her positive character. It adds to form stability, allows her to carry more weight, provides the width for both wide side decks for easy line-handling, and still leaves plenty of living space in the salon, and in the accommodations.

    Mainship 35 Trawler
    Three’s company and we like it like that! Mainship keeps it simple and you should, too.

    On the Flying Bridge

    As we move from top to bottom, the first place the 40% beam pays off is at the helm on the flying bridge. Mainship has three standard pedestal seats at the bridge, which is something we often don’t see on boats far bigger costing much more. That means that the skipper has two companions to help with the navigation and piloting and to keep good company. Isn’t that what boating is all about?Abaft the helm area is a “L”-shaped lounge seat with fiberglass table for more friends to sit, and a great place for lunch. The pictures of the boat in this article show the front half of the flying bridge fully enclosed with cruising canvas, something we recommend for anyone boating north of Morehead City. If you plan on boating south of there, then a Bimini top should be all you will need.

    Mainship 35 Trawler
    Abaft the helm area and outside the cruising canvas is the module for the refer, icemaker, sink and gas grill.

    The bridge on this boat is huge because Mainship’s designers have brought the flying bridge deck back over the cockpit. Not only does this give plenty of shade and protection from the elements on the aft deck, but it also provides lots of room on what we would normally call the “boat deck.” In the pictures here Mainship has placed a functional and attractive fiberglass module to house a refer, icemaker, sink and even a propane grill. Because the deck is so large there is plenty of room for several people to move around here.

    Mainship 35 Trawler
    The area of the flying bridge on a boat like this we usually call a “boat deck,” because you can place a tender there if you remove the fiberglass cabinet. Either way it is a very useful space.

    For boaters who will not be using the flying bridge for grilling, they may want to consider placing a tender with davit on the “boat deck.” Others may want to store other water toys there and possibly, a life raft. No matter what kind of cruising you want to do, we think you will find this little boat versatile.

    Mainship 35 Trawler

    In the Salon

    Mainship offers two versions of essentially the same layout in the salon. Both have the galley to port abaft the dinette. Opposite you can opt for two comfortable barrel seats or a 7’ long sofa. An option is a sofa than makes into a bed, which is probably a good idea if you go with this version. What Mainship does not seem to offer, and it surprises us, is a galley down version. We think a galley down version would be ideal for the cruising couple, or even a couple with kids because the sofa-bed becomes the second sleeping area.Please note that the Mainship comes standard with two helm stations, the one above, and a small one to starboard in the salon. Boaters, particularly beginning boaters, seem to like this arrangement because they can get out of inclement weather. There are three windshields forward and the middle one opens out to provide a breeze. There is a windscreen wiper on the starboard window.

    Mainship 35 Trawler
    We think Mainship has done a good job of installing this lower helm in a minimum of space. A leaning post can be seen at right.

    Regular readers know that we think lower helm stations on boats of this size are a waste of space if you have cruising canvass and isinglass on the flybridge. But on this boat, we agree with the Mainship's naval architects that putting a lower helm here is the best use of space. The reason is that the space is so small it cannot be used for much else, and there needs to be access to the side deck for easy egress when docking.

    Mainship 35 Trawler
    This dinette is bigger than you will find on many boats over 50’. Thank you for the 14’ beam!

    We have all been seated at dinettes on boats and know how tight they can be. Again the 14’2” beam of this little trawler-type boat pays off in comfortable room. Please note that the dinette on this 35 is nearly 4’8’ (1.43 m) wide -- that means 28” (.71 m) for each person on a side. That’s almost as good as at elbow room at the local IHop! The dinette is also raised so every one can see out (and there will be more crawl room below.)

    Mainship 35 Trawler
    We think this galley in cherry wood with stainless steel appliances looks up-scale, modern and well done. The deck is hardwood not carpet over plywood.

    The Staterooms

    Below, Mainship gives you a two stateroom version with the crawl-in double to port or two narrow singles, and the master forward. The bunks in the guest stateroom are 7’ long (2.15 m), and while you have to crawl in, there is full standing headroom in the area of the cabin near the hanging locker.Both the master queen and the guest beds have innerspring mattresses, not foam as used by a lot of builders. The head has a separate shower stall which is a bit unusual on a 35’ boat and the wives will appreciate that little detail. The cabins can be ordered with cherry hardwood flooring, and both provide changing room space and hanging lockers.

    One Engine or Two?

    The Mainship 35 comes standard with a single Yanmar 380-hp diesel engine, plus both a bow and a stern thruster. This is one of the few boats we know of that comes standard with both thrusters, and there is not a boat in this class standard with both, to our knowledge. This is a biggie. It means that even if this is your first single-screw boat, you should have no problem docking in most normal conditions. And with practice (with the thrusters in reserve as a fail-safe back-up) you can learn to dock the boat with only the single screw, your rudder, and a couple of lines (just like in the good old days.)

    Mainship 35 Trawler
    The master cabin forward. One way Mainship keeps the price low is not to put in expensive joinerwork next to the hull. This would be a good aftermarket project.

    A caveat:

    The thrusters are electric and low horsepower. Do not expect to lean on these thrusters for more than a minute or so at a time. Use them judiciously, with a bump, bump, bump and let momentum do as much work as possible. Electric thrusters overheat quickly and will shut off, or you can simply run your battery down. If you think of them as you would a starter motor, you will begin to understand their limitations. Remember, you have a strong diesel engine, a big propeller and a large rudder to do most of the work.The twin diesels available are Volvo Penta 225-hp units. If you opt for this power package, the boat comes with the only the bow thruster as standard.

    Mainship 35 Trawler
    The guest cabin will be a great place for cozy sleeping.

    Under normal cruising conditions the boat should be run at about 7 knots to optimize its economical operation. Remember this is a trawler, not a go-fast boat. With the Mainship 35 you can smell the daisies and enjoy the view rather than blasting past it. The 250 gallon (946 L) fuel tank should easily get you from place to place on most coasts.

    General Recommendation

    The boat is set up for easy cruising for a couple. There is handy fender storage in the transom and there is no need to have heavy lines and fenders to tax the weaker sex when docking. The door on the starboard side by the lower helm means that the skipper can ease the boat up to a dock and then hop out and throw lines ashore, making the boat easy to single-hand. Mainship has thoughtfully put a heavy-duty rub rail with stainless steel insert, so not to worry.We think this boat is a good way to get one’s feet wet with trawler speeds and the cruising lifestyle, with the minimum financial exposure. If you like it, then in a few years, trade up. If not, you will have had a great couple of seasons and sea stories for a lifetime. You only live once.
