Matching a modified vee Duckworth 30 2010 against a deep vee Duckworth Ultra Magnum Inboard 23 ft. 2008 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 Ultra Magnum Inboard 23 ft. 2008 measures 23,0 feet overall (2008), giving it roughly 20,0 additional feet of deck space compared to the Duckworth 30 2010 at 3,0 feet (2010). Weight tells a clearer story for trailering families: the Duckworth Ultra Magnum Inboard 23 ft. 2008 tips the scales at 361 lbs — 307 lbs less than the Duckworth 30 2010 at 54 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 30 2010 carries a rated maximum of 500 hp. Engine data for the Duckworth Ultra Magnum Inboard 23 ft. 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth 30 2010 carries 13 gallons versus 8 gallons in the Duckworth Ultra Magnum Inboard 23 ft. 2008. 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 30 2010 is rated for 9 passengers, while the Duckworth Ultra Magnum Inboard 23 ft. 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 30 2010 could be the deciding factor.
Bottom line: Choose the Duckworth 30 2010 if your priority is putting more people on the water — it handles 9 passengers and at 3,0 ft it has the deck room to back that rating up comfortably. The Duckworth Ultra Magnum Inboard 23 ft. 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
