When two boats share the same hull type — in this case both the Duckworth Pacific Navigator 200 Sterndrive 2009 and the Duckworth Ultra Magnum Inboard 22 ft. 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 Ultra Magnum Inboard 22 ft. 2008 measures 22,0 feet overall (2008), giving it roughly 20,0 additional feet of deck space compared to the Duckworth Pacific Navigator 200 Sterndrive 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator 200 Sterndrive 2009 tips the scales at 3 075 lbs — 2 744 lbs more than the Duckworth Ultra Magnum Inboard 22 ft. 2008 at 331 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.
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 Ultra Magnum Inboard 22 ft. 2008 at 22,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Duckworth Pacific Navigator 200 Sterndrive 2009 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
