Duckworth Magnum Inboard 21 ft. 2007 vs Duckworth Navigator Sport 195 2007 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Duckworth Magnum Inboard 21 ft. 2007 and the Duckworth Navigator Sport 195 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?

For family outings this is probably the sharpest distinction between the two. The Duckworth Magnum Inboard 21 ft. 2007 is rated for 6 passengers, while the Duckworth Navigator Sport 195 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Magnum Inboard 21 ft. 2007 could be the deciding factor.

Bottom line: Choose the Duckworth Magnum Inboard 21 ft. 2007 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Duckworth Navigator Sport 195 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
