Mainship 34 Trawler 2008 vs Mainship Expedition 2009 — A Close Look at Two Semi Displacements

When two boats share the same hull type — in this case both the Mainship 34 Trawler 2008 and the Mainship Expedition 2009 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 2008 at 36,0 ft versus Mainship Expedition 2009 at 38,0 ft. At 2 lbs and 24 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 370 hp, the Mainship 34 Trawler 2008 has a 110-hp advantage over the Mainship Expedition 2009's 260-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Mainship 34 Trawler 2008 carries 25 gallons versus 3 gallons in the Mainship Expedition 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 11 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: Performance buyers should lean toward the Mainship 34 Trawler 2008 and its 370-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Mainship Expedition 2009 with its 260-hp rating is the more economical daily driver.

Mainship 34 Trawler 2008 vs Mainship Expedition 2009 — Common Questions

Which is the larger boat — the Mainship 34 Trawler 2008 or the Mainship Expedition 2009?
The Mainship Expedition 2009 is the longer of the two at 38,0 feet overall. The Mainship 34 Trawler 2008 comes in at 36,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mainship 34 Trawler 2008 or the Mainship Expedition 2009?
For trailering, the Mainship 34 Trawler 2008 has the edge at 2 lbs dry weight versus 24 lbs for the Mainship Expedition 2009. 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.
Which boat can handle a bigger outboard?
The Mainship 34 Trawler 2008 is rated to a maximum of 370 hp, giving it the larger power ceiling. The Mainship Expedition 2009 tops out at 260 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Mainship 34 Trawler 2008 is Coast Guard rated for 11 passengers, while the Mainship Expedition 2009 is certified for 11. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Mainship 34 Trawler 2008 and Mainship Expedition 2009 share an 14 ft. 2 in. (4.32 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Mainship 34 Trawler 2008 or the Mainship Expedition 2009?
The Mainship 34 Trawler 2008 has the bigger tank at 25 gallons, versus 3 gallons on the Mainship Expedition 2009. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Mainship 34 Trawler 2008 and Mainship Expedition 2009 from the same manufacturer?
Yes — both the Mainship 34 Trawler 2008 and the Mainship Expedition 2009 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.
