Both the Duckworth 23 Ultra Magnum Inboard Jet 2009 and the Duckworth 255 2010 are deep-V designs, both built in aluminium, so 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 23 Ultra Magnum Inboard Jet 2009 at 23,0 ft versus Duckworth 255 2010 at 25,5 ft. Weight tells a clearer story for trailering families: the Duckworth 23 Ultra Magnum Inboard Jet 2009 tips the scales at 3 610 lbs - 890 lbs more than the Duckworth 255 2010 at 2 720 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 255 2010 tops out at 500 hp. Engine specs for the Duckworth 23 Ultra Magnum Inboard Jet 2009 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Duckworth 23 Ultra Magnum Inboard Jet 2009 carries 80 gallons versus 62 gallons in the Duckworth 255 2010. 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.
