Mainship 34 Trawler 2009 vs Mainship Pilot31 2010 — A Close Look at Two Semi Displacements

When two boats share the same hull type — in this case both the Mainship 34 Trawler 2009 and the Mainship Pilot31 2010 are semi displacement designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Mainship 34 Trawler 2009 at 34,0 ft versus Mainship Pilot31 2010 at 33,4 ft. Weight tells a clearer story for trailering families: the Mainship Pilot31 2010 tips the scales at 1 175 lbs — 1 173 lbs less than the Mainship 34 Trawler 2009 at 2 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 315 hp for the Mainship 34 Trawler 2009 and 315 hp for the Mainship Pilot31 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Mainship 34 Trawler 2009 carries 25 gallons versus 18 gallons in the Mainship Pilot31 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Mainship 34 Trawler 2009 and Mainship Pilot31 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Mainship 34 Trawler 2009 vs Mainship Pilot31 2010 — Common Questions

Which is the larger boat — the Mainship 34 Trawler 2009 or the Mainship Pilot31 2010?
The Mainship 34 Trawler 2009 is the longer of the two at 34,0 feet overall. The Mainship Pilot31 2010 comes in at 33,4 feet, making it roughly 0,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mainship 34 Trawler 2009 or the Mainship Pilot31 2010?
For trailering, the Mainship 34 Trawler 2009 has the edge at 2 lbs dry weight versus 1 175 lbs for the Mainship Pilot31 2010. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Mainship 34 Trawler 2009 is Coast Guard rated for 10 passengers, while the Mainship Pilot31 2010 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Mainship Pilot31 2010 measures 122" wide, compared to 17" for the Mainship 34 Trawler 2009. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Mainship 34 Trawler 2009 or the Mainship Pilot31 2010?
The Mainship 34 Trawler 2009 has the bigger tank at 25 gallons, versus 18 gallons on the Mainship Pilot31 2010. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Mainship 34 Trawler 2009 and Mainship Pilot31 2010 from the same manufacturer?
Yes — both the Mainship 34 Trawler 2009 and the Mainship Pilot31 2010 are built by Mainship. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
