When two boats share the same hull type — in this case both the Duckworth 19 2011 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 19 2011 at 19,0 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 — 224 lbs less than the Duckworth 19 2011 at 25 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 Pacific Navigator 215 SE 2008 is rated for 6 passengers, while the Duckworth 19 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Pacific Navigator 215 SE 2008 could be the deciding factor.
Bottom line: Choose the Duckworth Pacific Navigator 215 SE 2008 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Duckworth 19 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
