Mainship 34 Trawler Hardtop 2008 vs Mainship 35 Trawler 2010: A Close Look at Two Semi-Displacement Boats

Both the Mainship 34 Trawler Hardtop 2008 and the Mainship 35 Trawler 2010 are semi-displacement designs, both built in fibreglass, so 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 Hardtop 2008 at 36,0 ft versus Mainship 35 Trawler 2010 at 37,3 ft. Weight tells a clearer story for trailering families: the Mainship 35 Trawler 2010 tips the scales at 20 000 lbs - 1 000 lbs less than the Mainship 34 Trawler Hardtop 2008 at 19 000 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.

The power gap is worth calling out. Rated to 380 hp, the Mainship 35 Trawler 2010 has a 140-hp advantage over the Mainship 34 Trawler Hardtop 2008's 240-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 250 gal and 250 gal - so range won't be a tiebreaker here.

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 35 Trawler 2010 and its 380-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Mainship 34 Trawler Hardtop 2008 with its 240-hp rating is the more economical daily driver.

Mainship 34 Trawler Hardtop 2008 vs Mainship 35 Trawler 2010 - Common Questions

Which is the larger boat - the Mainship 34 Trawler Hardtop 2008 or the Mainship 35 Trawler 2010?
The Mainship 35 Trawler 2010 is the longer of the two at 37,3 feet overall. The Mainship 34 Trawler Hardtop 2008 comes in at 36,0 feet, making it roughly 1,3 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Mainship 34 Trawler Hardtop 2008 or the Mainship 35 Trawler 2010?
For trailering, the Mainship 34 Trawler Hardtop 2008 has the edge at 19 000 lbs dry weight versus 20 000 lbs for the Mainship 35 Trawler 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.
Which boat can handle a bigger outboard?
The Mainship 35 Trawler 2010 is rated to a maximum of 380 hp, giving it the larger power ceiling. The Mainship 34 Trawler Hardtop 2008 tops out at 240 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 Hardtop 2008 is Coast Guard rated for 11 passengers, while the Mainship 35 Trawler 2010 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.
Which boat is wider, and does it affect trailering?
The Mainship 35 Trawler 2010 measures 171" wide, compared to 170" for the Mainship 34 Trawler Hardtop 2008. 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.
How do the fuel tanks compare on the Mainship 34 Trawler Hardtop 2008 and Mainship 35 Trawler 2010?
Both boats carry similar fuel loads - 250 gallons and 250 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Mainship 34 Trawler Hardtop 2008 and Mainship 35 Trawler 2010 from the same manufacturer?
Yes - both the Mainship 34 Trawler Hardtop 2008 and the Mainship 35 Trawler 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.
