When two boats share the same hull type — in this case both the Duckworth Offshore 24 2013 and the Duckworth Ultra Magnum Inboard Jet 23 2013 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 Offshore 24 2013 at 26,0 ft versus Duckworth Ultra Magnum Inboard Jet 23 2013 at 23,0 ft. Weight tells a clearer story for trailering families: the Duckworth Ultra Magnum Inboard Jet 23 2013 tips the scales at 361 lbs — 317 lbs less than the Duckworth Offshore 24 2013 at 44 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 Offshore 24 2013 carries a rated maximum of 450 hp. Engine data for the Duckworth Ultra Magnum Inboard Jet 23 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth Offshore 24 2013 carries 13 gallons versus 8 gallons in the Duckworth Ultra Magnum Inboard Jet 23 2013. 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 Offshore 24 2013 at 26,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Duckworth Ultra Magnum Inboard Jet 23 2013 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.
