When two boats share the same hull type — in this case both the Duckworth 24 Ultra Magnum Inboard Jet 2009 and the Duckworth Pacific Navigator 215 SE 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?
On paper these two are close siblings in the size department — Duckworth 24 Ultra Magnum Inboard Jet 2009 at 24,0 ft versus Duckworth Pacific Navigator 215 SE 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Duckworth 24 Ultra Magnum Inboard Jet 2009 tips the scales at 372 lbs — 123 lbs more than the Duckworth Pacific Navigator 215 SE 2008 at 249 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.
For family outings this is probably the sharpest distinction between the two. The Duckworth 24 Ultra Magnum Inboard Jet 2009 is rated for 7 passengers, while the Duckworth Pacific Navigator 215 SE 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 24 Ultra Magnum Inboard Jet 2009 could be the deciding factor.
Bottom line: Choose the Duckworth 24 Ultra Magnum Inboard Jet 2009 if your priority is putting more people on the water — it handles 7 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Duckworth Pacific Navigator 215 SE 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
