Duckworth Offshore 24 2012 vs Duckworth Ultra Magnum Inboard 24 ft. 2008: A Close Look at Two Deep-V Boats

Both the Duckworth Offshore 24 2012 and the Duckworth Ultra Magnum Inboard 24 ft. 2008 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 Offshore 24 2012 at 26,0 ft versus Duckworth Ultra Magnum Inboard 24 ft. 2008 at 24,0 ft. Weight tells a clearer story for trailering families: the Duckworth Offshore 24 2012 tips the scales at 4 400 lbs - 680 lbs more than the Duckworth Ultra Magnum Inboard 24 ft. 2008 at 3 720 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 Offshore 24 2012 carries a rated maximum of 450 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 Offshore 24 2012 carries 175 gallons versus 80 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 Offshore 24 2012 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 Offshore 24 2012 vs Duckworth Ultra Magnum Inboard 24 ft. 2008 - Common Questions

Which is the larger boat - the Duckworth Offshore 24 2012 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
The Duckworth Offshore 24 2012 is the longer of the two at 26,0 feet overall. The Duckworth Ultra Magnum Inboard 24 ft. 2008 comes in at 24,0 feet, making it roughly 2,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Duckworth Offshore 24 2012 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
For trailering, the Duckworth Ultra Magnum Inboard 24 ft. 2008 has the edge at 3 720 lbs dry weight versus 4 400 lbs for the Duckworth Offshore 24 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 Offshore 24 2012 has a documented max rating of 450 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 Offshore 24 2012 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 Offshore 24 2012 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 Offshore 24 2012 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
The Duckworth Offshore 24 2012 has the bigger tank at 175 gallons, versus 80 gallons on the Duckworth Ultra Magnum Inboard 24 ft. 2008. That 95-gallon difference translates to roughly 285–475 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Duckworth Offshore 24 2012 and Duckworth Ultra Magnum Inboard 24 ft. 2008 from the same manufacturer?
Yes - both the Duckworth Offshore 24 2012 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.
