Both the Duckworth 215 2010 and the Duckworth Pacific Navigator 255 2013 are deep-V designs, both built in aluminium, so 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 Pacific Navigator 255 2013 measures 27,5 feet overall (2013), giving it roughly 6,0 additional feet of deck space compared to the Duckworth 215 2010 at 21,5 feet (2010). Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator 255 2013 tips the scales at 2 720 lbs - 450 lbs less than the Duckworth 215 2010 at 2 270 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 power gap is worth calling out. Rated to 500 hp, the Duckworth Pacific Navigator 255 2013 has a 250-hp advantage over the Duckworth 215 2010's 250-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 62 gal and 62 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Duckworth Pacific Navigator 255 2013 is rated for 8 passengers, while the Duckworth 215 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Pacific Navigator 255 2013 could be the deciding factor.
Bottom line: Choose the Duckworth Pacific Navigator 255 2013 if your priority is putting more people on the water - it handles 8 passengers and at 27,5 ft it has the deck room to back that rating up comfortably. The Duckworth 215 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
