Matching a modified vee Duckworth 721 2010 against a deep vee Duckworth Pacific Navigator 235 2009 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.
On paper these two are close siblings in the size department — Duckworth 721 2010 at 21,0 ft versus Duckworth Pacific Navigator 235 2009 at 23,5 ft. Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator 235 2009 tips the scales at 249 lbs — 233 lbs less than the Duckworth 721 2010 at 16 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 450 hp, the Duckworth Pacific Navigator 235 2009 has a 250-hp advantage over the Duckworth 721 2010's 200-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 235 2009 carries 62 gallons versus 42 gallons in the Duckworth 721 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 Pacific Navigator 235 2009 is rated for 7 passengers, while the Duckworth 721 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 Pacific Navigator 235 2009 could be the deciding factor.
Bottom line: Choose the Duckworth Pacific Navigator 235 2009 if your priority is putting more people on the water — it handles 7 passengers and at 23,5 ft it has the deck room to back that rating up comfortably. The Duckworth 721 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.
