Matching a deep vee Duckworth 175 Sport 2010 against a modified vee Duckworth Pro 721 2013 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 Pro 721 2013 measures 21,0 feet overall (2013), giving it roughly 3,5 additional feet of deck space compared to the Duckworth 175 Sport 2010 at 17,5 feet (2010). Weight tells a clearer story for trailering families: the Duckworth 175 Sport 2010 tips the scales at 1 455 lbs — 1 439 lbs more than the Duckworth Pro 721 2013 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 Duckworth 175 Sport 2010 carries a rated maximum of 115 hp. Engine data for the Duckworth Pro 721 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.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 Pro 721 2013 is rated for 6 passengers, while the Duckworth 175 Sport 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 Pro 721 2013 could be the deciding factor.
Bottom line: Choose the Duckworth Pro 721 2013 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Duckworth 175 Sport 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.
