Matching a deep vee Duckworth 18 2010 against a modified vee Duckworth 723 2010 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 723 2010 measures 23,0 feet overall (2010), giving it roughly 5,0 additional feet of deck space compared to the Duckworth 18 2010 at 18,0 feet (2010). Weight tells a clearer story for trailering families: the Duckworth 18 2010 tips the scales at 2 375 lbs — 2 358 lbs more than the Duckworth 723 2010 at 17 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 250 hp, the Duckworth 723 2010 has a 135-hp advantage over the Duckworth 18 2010's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 42 gal and 42 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Duckworth 723 2010 is rated for 7 passengers, while the Duckworth 18 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 723 2010 could be the deciding factor.
Bottom line: Choose the Duckworth 723 2010 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Duckworth 18 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
