Mainship Expedition 2009 vs Mainship Pilot 34 2007 — Same Brand, Different Boat

The Mainship Expedition 2009 vs Mainship Pilot 34 2007 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.

On paper these two are close siblings in the size department — Mainship Expedition 2009 at 38,0 ft versus Mainship Pilot 34 2007 at 36,0 ft. At 24 lbs and 16 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.

The Mainship Expedition 2009 carries a rated maximum of 260 hp. Engine data for the Mainship Pilot 34 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Mainship Pilot 34 2007 carries 25 gallons versus 3 gallons in the Mainship Expedition 2009. 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.

Bottom line: The Mainship Expedition 2009 and Mainship Pilot 34 2007 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Mainship Expedition 2009 vs Mainship Pilot 34 2007 — Common Questions

Which is the larger boat — the Mainship Expedition 2009 or the Mainship Pilot 34 2007?
The Mainship Expedition 2009 is the longer of the two at 38,0 feet overall. The Mainship Pilot 34 2007 comes in at 36,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mainship Expedition 2009 or the Mainship Pilot 34 2007?
For trailering, the Mainship Pilot 34 2007 has the edge at 16 lbs dry weight versus 24 lbs for the Mainship Expedition 2009. 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.
What is the maximum horsepower rating for these boats?
The Mainship Expedition 2009 has a documented max rating of 260 hp. Engine specifications for the Mainship Pilot 34 2007 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Mainship Expedition 2009 is Coast Guard rated for 11 passengers, while the Mainship Pilot 34 2007 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 Pilot 34 2007 measures 147" wide, compared to 17" for the Mainship Expedition 2009. 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.
Which boat has the larger fuel tank — the Mainship Expedition 2009 or the Mainship Pilot 34 2007?
The Mainship Pilot 34 2007 has the bigger tank at 25 gallons, versus 3 gallons on the Mainship Expedition 2009. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Mainship Expedition 2009 and Mainship Pilot 34 2007 from the same manufacturer?
Yes — both the Mainship Expedition 2009 and the Mainship Pilot 34 2007 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.
