Duckworth Ultra Magnum Inboard 24 ft. 2008 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 Ultra Magnum Inboard 24 ft. 2008 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 Ultra Magnum Inboard 24 ft. 2008 at 24,0 ft versus Duckworth Ultra Magnum Inboard Jet 23 2012 at 23,0 ft. At 372 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.

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 Ultra Magnum Inboard 24 ft. 2008 and Duckworth Ultra Magnum Inboard Jet 23 2012 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 Ultra Magnum Inboard 24 ft. 2008 vs Duckworth Ultra Magnum Inboard Jet 23 2012 — Common Questions

Which is the larger boat — the Duckworth Ultra Magnum Inboard 24 ft. 2008 or the Duckworth Ultra Magnum Inboard Jet 23 2012?
The Duckworth Ultra Magnum Inboard 24 ft. 2008 is the longer of the two at 24,0 feet overall. The Duckworth Ultra Magnum Inboard Jet 23 2012 comes in at 23,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Duckworth Ultra Magnum Inboard 24 ft. 2008 or the Duckworth Ultra Magnum Inboard Jet 23 2012?
For trailering, the Duckworth Ultra Magnum Inboard Jet 23 2012 has the edge at 361 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.
How many people can each boat hold?
The Duckworth Ultra Magnum Inboard 24 ft. 2008 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 Ultra Magnum Inboard 24 ft. 2008 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.
How do the fuel tanks compare on the Duckworth Ultra Magnum Inboard 24 ft. 2008 and Duckworth Ultra Magnum Inboard Jet 23 2012?
Both boats carry similar fuel loads — 8 gallons and 8 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Duckworth Ultra Magnum Inboard 24 ft. 2008 and Duckworth Ultra Magnum Inboard Jet 23 2012 from the same manufacturer?
Yes — both the Duckworth Ultra Magnum Inboard 24 ft. 2008 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.
