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 Sport 20 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?

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 Sport 20 2013 at 21,9 ft. Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator Sport 20 2013 tips the scales at 1 635 lbs — 1 263 lbs less than the Duckworth 24 Ultra Magnum Inboard Jet 2009 at 372 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 Pacific Navigator Sport 20 2013 tops out at 200 hp. Engine specs for the Duckworth 24 Ultra Magnum Inboard Jet 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Duckworth Pacific Navigator Sport 20 2013 carries 42 gallons versus 8 gallons in the Duckworth 24 Ultra Magnum Inboard Jet 2009. 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 24 Ultra Magnum Inboard Jet 2009 is rated for 7 passengers, while the Duckworth Pacific Navigator Sport 20 2013 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.
