Duckworth Magnum Inboard 23 ft. 2007 vs Duckworth Ultra Magnum Inboard Jet 24 2013 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Duckworth Magnum Inboard 23 ft. 2007 and the Duckworth Ultra Magnum Inboard Jet 24 2013 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?

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 Magnum Inboard 23 ft. 2007 and Duckworth Ultra Magnum Inboard Jet 24 2013 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.

How many people can each boat hold?
The Duckworth Magnum Inboard 23 ft. 2007 is Coast Guard rated for 7 passengers, while the Duckworth Ultra Magnum Inboard Jet 24 2013 is certified for 7.

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 Magnum Inboard 23 ft. 2007 and Duckworth Ultra Magnum Inboard Jet 24 2013?
