Duckworth 255 2011 vs Duckworth Ultra Magnum Inboard 24 ft. 2008 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Duckworth 255 2011 and the Duckworth Ultra Magnum Inboard 24 ft. 2008 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 2011 at 25,5 ft versus Duckworth Ultra Magnum Inboard 24 ft. 2008 at 24,0 ft. At 272 lbs and 372 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 2011 carries a rated maximum of 500 hp. Engine data for the Duckworth Ultra Magnum Inboard 24 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 255 2011 carries 62 gallons versus 8 gallons in the Duckworth Ultra Magnum Inboard 24 ft. 2008. 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 2011 and Duckworth Ultra Magnum Inboard 24 ft. 2008 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Duckworth 255 2011 vs Duckworth Ultra Magnum Inboard 24 ft. 2008 — Common Questions

Which is the larger boat — the Duckworth 255 2011 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
The Duckworth 255 2011 is the longer of the two at 25,5 feet overall. The Duckworth Ultra Magnum Inboard 24 ft. 2008 comes in at 24,0 feet, making it roughly 1,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Duckworth 255 2011 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
For trailering, the Duckworth 255 2011 has the edge at 272 lbs dry weight versus 372 lbs for the Duckworth Ultra Magnum Inboard 24 ft. 2008. 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 2011 has a documented max rating of 500 hp. Engine specifications for the Duckworth Ultra Magnum Inboard 24 ft. 2008 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 2011 is Coast Guard rated for 7 passengers, while the Duckworth Ultra Magnum Inboard 24 ft. 2008 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 2011 and Duckworth Ultra Magnum Inboard 24 ft. 2008 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 2011 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
The Duckworth 255 2011 has the bigger tank at 62 gallons, versus 8 gallons on the Duckworth Ultra Magnum Inboard 24 ft. 2008. 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 2011 and Duckworth Ultra Magnum Inboard 24 ft. 2008 from the same manufacturer?
Yes — both the Duckworth 255 2011 and the Duckworth Ultra Magnum Inboard 24 ft. 2008 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.
