Matching a deep vee Duckworth 175 Sport 2010 against a modified vee Duckworth 28 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 28 2010 measures 28,0 feet overall (2010), giving it roughly 10,5 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 — 1 404 lbs more than the Duckworth 28 2010 at 51 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 28 2010 has a 385-hp advantage over the Duckworth 175 Sport 2010'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 175 Sport 2010 carries 42 gallons versus 13 gallons in the Duckworth 28 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 28 2010 is rated for 8 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 28 2010 could be the deciding factor.
Bottom line: Choose the Duckworth 28 2010 if your priority is putting more people on the water — it handles 8 passengers and at 28,0 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.
