When two boats share the same hull type — in this case both the Duckworth 20 2010 and the Duckworth 28 2011 are deep vee designs with aluminum construction — 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 26,0 additional feet of deck space compared to the Duckworth 20 2010 at 2,0 feet (2010). At 27 lbs and 51 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 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 20 2010 carries 62 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 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.
