Mainship 40 Trawler 2007 vs Mainship Pilot31 2008 — Same Brand, Different Boat

The Mainship 40 Trawler 2007 vs Mainship Pilot31 2008 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Mainship 40 Trawler 2007 measures 41,0 feet overall (2007), giving it roughly 6,0 additional feet of deck space compared to the Mainship Pilot31 2008 at 35,0 feet (2008). Weight tells a clearer story for trailering families: the Mainship Pilot31 2008 tips the scales at 1 175 lbs — 1 151 lbs less than the Mainship 40 Trawler 2007 at 24 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 Mainship Pilot31 2008 tops out at 315 hp. Engine specs for the Mainship 40 Trawler 2007 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Mainship Pilot31 2008 carries 18 gallons versus 3 gallons in the Mainship 40 Trawler 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Mainship 40 Trawler 2007 is rated for 12 passengers, while the Mainship Pilot31 2008 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mainship 40 Trawler 2007 could be the deciding factor.

Bottom line: Choose the Mainship 40 Trawler 2007 if your priority is putting more people on the water — it handles 12 passengers and at 41,0 ft it has the deck room to back that rating up comfortably. The Mainship Pilot31 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

The Mainship 40 Trawler 2007 is the longer of the two at 41,0 feet overall. The Mainship Pilot31 2008 comes in at 35,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

How many people can each boat hold?
The Mainship 40 Trawler 2007 is Coast Guard rated for 12 passengers, while the Mainship Pilot31 2008 is certified for 10.
