Matching a deep vee Duckworth 28 2011 against a modified vee Duckworth 723 2010 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 28 2011 measures 28,0 feet overall (2011), giving it roughly 5,0 additional feet of deck space compared to the Duckworth 723 2010 at 23,0 feet (2010). At 51 lbs and 17 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 power gap is worth calling out. Rated to 500 hp, the Duckworth 28 2011 has a 250-hp advantage over the Duckworth 723 2010's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Duckworth 723 2010 carries 42 gallons versus 13 gallons in the Duckworth 28 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 28 2011 is rated for 8 passengers, while the Duckworth 723 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 28 2011 could be the deciding factor.
Bottom line: Choose the Duckworth 28 2011 if your priority is putting more people on the water — it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Duckworth 723 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
