When two boats share the same hull type — in this case both the Duckworth 20 2010 and the Duckworth Navigator Sport 20 2013 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 Navigator Sport 20 2013 measures 20,3 feet overall (2013), giving it roughly 18,3 additional feet of deck space compared to the Duckworth 20 2010 at 2,0 feet (2010). At 27 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 Duckworth Navigator Sport 20 2013 tops out at 15 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 42 gallons in the Duckworth Navigator Sport 20 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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 Duckworth Navigator Sport 20 2013 at 20,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Duckworth 20 2010 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
