Both the Duckworth 20 2010 and the Duckworth 28 2011 are deep-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Duckworth 28 2011 measures 28,0 feet overall (2011), giving it roughly 8,0 additional feet of deck space compared to the Duckworth 20 2010 at 20,0 feet (2010). Weight tells a clearer story for trailering families: the Duckworth 28 2011 tips the scales at 5 100 lbs - 2 400 lbs less than the Duckworth 20 2010 at 2 700 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 28 2011 tops out at 500 hp. Engine specs for the Duckworth 20 2010 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Duckworth 28 2011 carries 130 gallons versus 62 gallons in the Duckworth 20 2010. 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 20 2010 caps at 6. 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 20 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
