Duckworth 21 2011 vs Duckworth Magnum Inboard 21 ft. 2007 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Duckworth 21 2011 and the Duckworth Magnum Inboard 21 ft. 2007 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 6 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 21 2011 and Duckworth Magnum Inboard 21 ft. 2007 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.
