When two boats share the same hull type — in this case both the Duckworth 21 2010 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 21 2010 at 21,0 ft versus Duckworth Pacific Navigator 215 SE 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator 215 SE 2008 tips the scales at 249 lbs — 221 lbs less than the Duckworth 21 2010 at 28 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.
