Matching a modified vee Duckworth 26 2010 against a deep vee Duckworth Pacific Navigator Sport 18 2012 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 26 2010 measures 26,0 feet overall (2010), giving it roughly 5,7 additional feet of deck space compared to the Duckworth Pacific Navigator Sport 18 2012 at 20,3 feet (2012). Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator Sport 18 2012 tips the scales at 1 455 lbs — 1 408 lbs less than the Duckworth 26 2010 at 47 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 power gap is worth calling out. Rated to 500 hp, the Duckworth 26 2010 has a 385-hp advantage over the Duckworth Pacific Navigator Sport 18 2012's 115-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 Pacific Navigator Sport 18 2012 carries 42 gallons versus 13 gallons in the Duckworth 26 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 26 2010 is rated for 7 passengers, while the Duckworth Pacific Navigator Sport 18 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 26 2010 could be the deciding factor.
Bottom line: Choose the Duckworth 26 2010 if your priority is putting more people on the water — it handles 7 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Duckworth Pacific Navigator Sport 18 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
