When two boats share the same hull type — in this case both the Duckworth 22 Ultra Magnum Inboard Jet 2009 and the Duckworth Navigator Sport 175 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?

Size is the most obvious dividing line here. The Duckworth 22 Ultra Magnum Inboard Jet 2009 measures 22,0 feet overall (2009), giving it roughly 5,0 additional feet of deck space compared to the Duckworth Navigator Sport 175 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Duckworth 22 Ultra Magnum Inboard Jet 2009 tips the scales at 331 lbs — 317 lbs more than the Duckworth Navigator Sport 175 2008 at 14 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 Navigator Sport 175 2008 tops out at 115 hp. Engine specs for the Duckworth 22 Ultra Magnum Inboard Jet 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Duckworth 22 Ultra Magnum Inboard Jet 2009 carries 62 gallons versus 42 gallons in the Duckworth Navigator Sport 175 2008. 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 22 Ultra Magnum Inboard Jet 2009 is rated for 6 passengers, while the Duckworth Navigator Sport 175 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 22 Ultra Magnum Inboard Jet 2009 could be the deciding factor.
