When two boats share the same hull type — in this case both the Duckworth 255 2010 and the Duckworth Ultra Magnum Inboard Jet 23 2012 are deep vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Duckworth 255 2010 at 25,5 ft versus Duckworth Ultra Magnum Inboard Jet 23 2012 at 23,0 ft. At 272 lbs and 361 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The Duckworth 255 2010 carries a rated maximum of 500 hp. Engine data for the Duckworth Ultra Magnum Inboard Jet 23 2012 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth 255 2010 carries 62 gallons versus 8 gallons in the Duckworth Ultra Magnum Inboard Jet 23 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Duckworth 255 2010 at 25,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Duckworth Ultra Magnum Inboard Jet 23 2012 at 23,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
