When two boats share the same hull type — in this case both the Duckworth 20 2010 and the Duckworth Pacific Navigator Sport 18 2012 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 Pacific Navigator Sport 18 2012 measures 20,3 feet overall (2012), giving it roughly 18,3 additional feet of deck space compared to the Duckworth 20 2010 at 2,0 feet (2010). Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator Sport 18 2012 tips the scales at 1 455 lbs — 1 428 lbs less than the Duckworth 20 2010 at 27 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 Pacific Navigator Sport 18 2012 tops out at 115 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 Pacific Navigator Sport 18 2012. 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 Pacific Navigator Sport 18 2012 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.
