Brief Summary

The Mainship 414 Trawler could be just the ticket for folks hoping to embark on long cruises, maybe following the Great Circle Route through the American heartland, voyaging up the inside passage to Alaska or, our favorite, ambling among the islands of the Bahamas. At 41' 4" (12.6 m) LOA, the two-stateroom 414T will accommodate just the right number of people for a boat her size, in our opinion.

Captain's Report

Mainship 414T
Americans like living on the flying bridge, so the Mainship designers created one atop the 414T that rivals the cabin for comfort. There's not only lots of seating, but also a "summer galley" that we think most cooks will prefer to the one belowdecks. We like the covered side- and aft decks, and her jaunty profile with a broken sheerline, too.

A Trawler By Any Other Name

When we tested this boat a while back, she was called the Expedition Trawler, maybe a more evocative name than 414 Trawler. But Mainship has renamed all its models to reflect their overall length, and since this boat is 41' 4", she became the 414T. Otherwise she's the same boat as the earlier Expedition: A single-screw diesel cruiser with comfortable accommodations for four that will take you 252 n.m. (467 km.) on a 300-gal. (1,136 L) fuel capacity (with a 10% reserve) at a respectable cruising speed of 15.9 kt. (29.5 kph). Top speed in our test: 16.7 kt. (30.9 kph) with standard power, a 380-hp Yanmar 6LY3-UTP.

Mainship 414T
This is a no-nonsense helm, with a single swivel seat on the centerline and room for two nav units flanking the wheel. Co-pilots can sit on either side, with clear sightlines forward but without infringing on the helmsman's space. In total, there's seating for eight on the flying bridge.

In our book, 290 miles doesn't make for much of an expedition – but did you ever hear of an expedition taking place at almost 16 knots? No, neither have we. You can have long range, though: Slow the 414T to traditional trawler speed, say 7 knots, and you should be able to coax over 800 n.m. out of the same amount of fuel. That's enough leg to take you quite a ways off the beaten path – maybe through the remote islands of the Caribbean or to the far corners of the Med -- or let you cruise on the beaten path without having to stop for fuel every day. Fuel consumption increases quickly beyond 7.5 knots, so if you want maximum range, go easy on the throttle. At 8.5 mph or 7.3 knots, the boat has a range of 713 statute miles or 620 nautical miles, according to our tests. That means that you can get from Florida to New England at these speeds in the ICW on two loads of fuel. How's that for economy?

Mainship 414T
The lower helm has lots of space for flush-mounting electronics, with easy access to the starboard side deck via a sliding door. But why two joysticks? Mainship installs both bow and stern thrusters as standard equipment in all single-screw 414Ts. (Twin 220-hp diesels are optional, adds $31,250.)

Maybe Mainship's name change was smart, after all: The 414T can be a leisurely, long-range traditional trawler, but also a fast cruiser in waters where harbors, and fuel docks, are plentiful. We suspect most people will prefer the latter. This boat is not really up to a real "expedition" to someplace like, say, Tahiti. There are other boats for that kind of work and they are both heavier, larger and far more expensive.

Comfort for Four in Two

Belowdecks, the 414T holds no surprises: The layout is what we've come to expect in a yacht of this size and type, i.e., with traditional midships engines. There's a master stateroom forward, with the typical centerline peninsula berth, a twin-bunk cabin to port, head compartment to starboard. The galley is in the salon, taking space from there but adding it in the accommodations. What else can you do when you want to fit in two cabins? We don't know – this arrangement works fine for us.

Mainship 414T
The twin berths in the guest cabin are tucked under the galley, but your legs won't mind. There's standing headroom near the cabin door for dressing/undressing, and a hanging locker. The salon looks spacious in this plan, even with the L-shaped galley here.

Mainship builds the 414T's joinery in cherry, a light-colored wood that, in concert with a white overhead, makes the most of the large cabin windows to keep the salon bright. Air conditioning is optional ($14,000), as is a central vacuum system ($950). Folks serious about cruising out of season or to the Great White North can have diesel cabin heating (ask your Mainship dealer for the price).

Mainship 414T

The salon benefits from large cabin windows port and starboard and light-colored cherry joinery and upholstery, too. We like the pair of plush-looking swivel chairs. Everyday engine access is through a centerline hatch in the sole; adjacent panels are removable for major repairs or maintenance.

Mainship 414T
Looking aft in the salon. Cockpit access is via centerline double doors; there's room outside for a couple of deck chairs. The table and settee convert to a double berth. There's a 26" flat-panel TV, tied into the stereo system with its DVD player, and stowage in overhead lockers port and starboard.

Galley Up, Staterooms Down

Placing the galley in the salon opens up space belowdecks for sleeping; otherwise it would be extremely cramped down there with two cabins. But the salon is big enough to absorb the L-shaped galley, opposite the lower helm station, without crimping the crew's style. And the cook will prefer it, too: No carrying plates up and down steps, no banishment belowdecks when everyone else is having fun in the salon.

Mainship 414T
The standard galley has drawer-style fridge and freezer, both dual voltage, a three-burner electric stove/oven and a microwave oven mounted high up where it's useful. We don't like under-counter microwaves – who wants to bend over that far? -- but some builders put them there. A propane stove is optional; since the Kohler 9-kW genset adds $16,000 to the price, we'd consider the $3,180 gas-stove option, especially if we planned long-range cruising off the grid.
Mainship 414T
The master berth has a queen-sized innerspring mattress and two hanging lockers, but we'd like shelves near the head of the berth to put our book and glasses at night. Individual high-intensity reading lights are nice, though. There are drawers under the berth for added stowage.
Mainship 414T
For family cruising, the guest stateroom can hold a couple of kids; for expeditions, a team of wreck-exploring divers, naturalists or even ex-Navy SEALS, if you're really going into the wild. The rod under the lockers looks of minimal use to us, other than to throw clothes over to keep them off the cabin sole – maybe that's the idea. There is a separate hanging locker. A filler cushion is optional ($515).

Prices and Our Opinion

Base price of the Mainship 414 Trawler is $393,207 with a single 380-hp Yanmar 6LY3-UTP diesel spinning a conventional shaft and prop. Folks worried about handing a single-screw boat will have both bow and stern thrusters to help out – both are standard. Or opt for twin 220-hp Yanmar 6BY2-220 diesels ($31,250); you'll lose the stern thruster. We'd stick with the single.

Mainship 414T
Mainship offers an optional Summer Galley ($5,514) on the flying bridge – with a propane grill, icemaker and sink. It should serve most cooking needs in fine weather.

A Bimini top and full enclosure are optional ($4,257 and $6,386 respectively) -- get them as you'll want protection on the flying bridge, from the sun at least. A windlass adds $3,714; a 35-lb plow anchor and chain/rope rode are standard. Mainship also includes a bell, docklines and fenders as standard, and a boat hook, too.Even with a full array of options, a Mainship 414 Trawler should list somewhere in the mid-$400K range, not a bad price for a boat of this size. Mainship is known for building value into their boats, and this one, apparently, is no exception. The single diesel helps, too, and will reduce maintenance costs.

Mainship 414T
A 35-lb plow anchor and rode are included as standard, but the 414T's pulpit will carry two hooks – we think a second plow would fit best, maybe something around 60 lbs for extra holding power. No boat should sail without two anchors.


For comparison, we found a number of similar trawler yachts from middle-of-the-road builders, most based in the Far East, with price tags in the same range as the Mainship. Choosing among them is difficult to do on paper. But move into the "big names" and the boats that are designed for ocean crossings, or are much more "up-market" brands and the prices skyrocket: A same-size trawler yacht from a famous prestigious brand, but with twin Zeus pods, runs around $744,000. A single-screw tug-yacht of similar size, again from a top builder, costs around $722,000. These boats are generally heavier and have much more teak and wood in them and certainly more man-hours of labor. Mainship is a price-point builder and wise consumers would carefully consider how much boat they really need for the mission intended. If you are not going to be like Jacques Cousteau, then perhaps it is just what you need. The bottom line: We'd surely check out the Mainship 414 Trawler before buying a similar boat, whether we were planning long cruises or just a trip across the bay.
