Both the Duckworth 26 2011 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?
On paper these two are close siblings in the size department - Duckworth 26 2011 at 26,0 ft versus Duckworth Pacific Navigator 255 2013 at 27,5 ft. Weight tells a clearer story for trailering families: the Duckworth 26 2011 tips the scales at 4 700 lbs - 1 980 lbs more than the Duckworth Pacific Navigator 255 2013 at 2 720 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 share a closely matched power ceiling - 500 hp for the Duckworth 26 2011 and 500 hp for the Duckworth Pacific Navigator 255 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Duckworth 26 2011 carries 130 gallons versus 62 gallons in the Duckworth Pacific Navigator 255 2013. 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 Pacific Navigator 255 2013 is rated for 8 passengers, while the Duckworth 26 2011 caps at 7. 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 26 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
