Mainship 40 Trawler 2007 vs Mainship Expedition 2009 — Common Questions

Which is the larger boat — the Mainship 40 Trawler 2007 or the Mainship Expedition 2009?
The Mainship 40 Trawler 2007 is the longer of the two at 41,0 feet overall. The Mainship Expedition 2009 comes in at 38,0 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mainship 40 Trawler 2007 or the Mainship Expedition 2009?
For trailering, the Mainship Expedition 2009 has the edge at 24 lbs dry weight versus 24 lbs for the Mainship 40 Trawler 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows.

How many people can each boat hold?
The Mainship 40 Trawler 2007 is Coast Guard rated for 12 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 40 Trawler 2007 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.
How do the fuel tanks compare on the Mainship 40 Trawler 2007 and Mainship Expedition 2009?
Both boats carry similar fuel loads — 3 gallons and 3 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Yes — both the Mainship 40 Trawler 2007 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.
