Both the Duckworth 28 2011 and the Duckworth Pacific Navigator 235 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 28 2011 at 28,0 ft versus Duckworth Pacific Navigator 235 2013 at 25,5 ft. Weight tells a clearer story for trailering families: the Duckworth 28 2011 tips the scales at 5 100 lbs - 2 610 lbs more than the Duckworth Pacific Navigator 235 2013 at 2 490 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 28 2011 has a 50-hp advantage over the Duckworth Pacific Navigator 235 2013's 450-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Duckworth 28 2011 carries 130 gallons versus 62 gallons in the Duckworth Pacific Navigator 235 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 28 2011 is rated for 8 passengers, while the Duckworth Pacific Navigator 235 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 28 2011 could be the deciding factor.
Bottom line: Choose the Duckworth 28 2011 if your priority is putting more people on the water - it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Duckworth Pacific Navigator 235 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
