Both the Mainship 35 Trawler 2010 and the Mainship Expedition 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 35 Trawler 2010 at 37,3 ft versus Mainship Expedition 2010 at 38,3 ft. Weight tells a clearer story for trailering families: the Mainship Expedition 2010 tips the scales at 24 000 lbs - 4 000 lbs less than the Mainship 35 Trawler 2010 at 20 000 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.

Both boats share a closely matched power ceiling - 380 hp for the Mainship 35 Trawler 2010 and 380 hp for the Mainship Expedition 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 Expedition 2010 carries 300 gallons versus 250 gallons in the Mainship 35 Trawler 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 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.
