When two boats share the same hull type — in this case both the Mainship 35 Trawler 2010 and the Mainship Expedition 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 35 Trawler 2010 at 37,3 ft versus Mainship Expedition 2010 at 38,3 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.

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 35 Trawler 2010 carries 25 gallons versus 3 gallons in the Mainship Expedition 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.
