Matching a deep vee Duckworth 255 2010 against a modified vee Duckworth 721 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Duckworth 255 2010 measures 25,5 feet overall (2010), giving it roughly 4,5 additional feet of deck space compared to the Duckworth 721 2011 at 21,0 feet (2011). Weight tells a clearer story for trailering families: the Duckworth 255 2010 tips the scales at 272 lbs — 256 lbs more than the Duckworth 721 2011 at 16 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 Duckworth 255 2010 carries a rated maximum of 500 hp. Engine data for the Duckworth 721 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth 255 2010 carries 62 gallons versus 42 gallons in the Duckworth 721 2011. 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 Duckworth 255 2010 is rated for 7 passengers, while the Duckworth 721 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 255 2010 could be the deciding factor.
Bottom line: Choose the Duckworth 255 2010 if your priority is putting more people on the water — it handles 7 passengers and at 25,5 ft it has the deck room to back that rating up comfortably. The Duckworth 721 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
