Duckworth Offshore 26 2012 vs Duckworth Ultra Magnum Inboard 24 ft. 2008 — Which Deep Vee Fits Your Needs?

When two boats share the same hull type — in this case both the Duckworth Offshore 26 2012 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?

Size is the most obvious dividing line here. The Duckworth Offshore 26 2012 measures 28,0 feet overall (2012), giving it roughly 4,0 additional feet of deck space compared to the Duckworth Ultra Magnum Inboard 24 ft. 2008 at 24,0 feet (2008). Weight tells a clearer story for trailering families: the Duckworth Ultra Magnum Inboard 24 ft. 2008 tips the scales at 372 lbs — 325 lbs less than the Duckworth Offshore 26 2012 at 47 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 26 2012 carries a rated maximum of 5 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 26 2012 carries 175 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.

For family outings this is probably the sharpest distinction between the two. The Duckworth Offshore 26 2012 is rated for 8 passengers, while the Duckworth Ultra Magnum Inboard 24 ft. 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Offshore 26 2012 could be the deciding factor.

Bottom line: Choose the Duckworth Offshore 26 2012 if your priority is putting more people on the water — it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Duckworth Ultra Magnum Inboard 24 ft. 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Duckworth Offshore 26 2012 vs Duckworth Ultra Magnum Inboard 24 ft. 2008 — Common Questions

Which is the larger boat — the Duckworth Offshore 26 2012 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
The Duckworth Offshore 26 2012 is the longer of the two at 28,0 feet overall. The Duckworth Ultra Magnum Inboard 24 ft. 2008 comes in at 24,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Duckworth Offshore 26 2012 or the Duckworth Ultra Magnum Inboard 24 ft. 2008?
For trailering, the Duckworth Offshore 26 2012 has the edge at 47 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 Offshore 26 2012 has a documented max rating of 5 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 26 2012 is Coast Guard rated for 8 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 26 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.

The Duckworth Offshore 26 2012 has the bigger tank at 175 gallons, versus 8 gallons on the Duckworth Ultra Magnum Inboard 24 ft. 2008. That 167-gallon difference translates to roughly 501–835 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Duckworth Offshore 26 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.
