Duckworth 255 2010 vs Duckworth Ultra Magnum Inboard Jet 23 2012 — A Close Look at Two Deep Vees

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.

Duckworth 255 2010 vs Duckworth Ultra Magnum Inboard Jet 23 2012 — Common Questions

Which is the larger boat — the Duckworth 255 2010 or the Duckworth Ultra Magnum Inboard Jet 23 2012?
The Duckworth 255 2010 is the longer of the two at 25,5 feet overall. The Duckworth Ultra Magnum Inboard Jet 23 2012 comes in at 23,0 feet, making it roughly 2,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Duckworth 255 2010 or the Duckworth Ultra Magnum Inboard Jet 23 2012?
For trailering, the Duckworth 255 2010 has the edge at 272 lbs dry weight versus 361 lbs for the Duckworth Ultra Magnum Inboard Jet 23 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Duckworth 255 2010 has a documented max rating of 500 hp. Engine specifications for the Duckworth Ultra Magnum Inboard Jet 23 2012 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Duckworth 255 2010 is Coast Guard rated for 7 passengers, while the Duckworth Ultra Magnum Inboard Jet 23 2012 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Duckworth 255 2010 and Duckworth Ultra Magnum Inboard Jet 23 2012 share an 102 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Duckworth 255 2010 or the Duckworth Ultra Magnum Inboard Jet 23 2012?
The Duckworth 255 2010 has the bigger tank at 62 gallons, versus 8 gallons on the Duckworth Ultra Magnum Inboard Jet 23 2012. That 54-gallon difference translates to roughly 162–270 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Duckworth 255 2010 and Duckworth Ultra Magnum Inboard Jet 23 2012 from the same manufacturer?
Yes — both the Duckworth 255 2010 and the Duckworth Ultra Magnum Inboard Jet 23 2012 are built by Duckworth. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
