Both the Duckworth 255 2010 and the Duckworth Navigator Sport 195 2008 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 255 2010 measures 25,5 feet overall (2010), giving it roughly 6,5 additional feet of deck space compared to the Duckworth Navigator Sport 195 2008 at 19,0 feet (2008). Weight tells a clearer story for trailering families: the Duckworth 255 2010 tips the scales at 2 720 lbs - 1 170 lbs more than the Duckworth Navigator Sport 195 2008 at 1 550 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 255 2010 has a 350-hp advantage over the Duckworth Navigator Sport 195 2008's 150-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 255 2010 carries 62 gallons versus 42 gallons in the Duckworth Navigator Sport 195 2008. 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 255 2010 is rated for 7 passengers, while the Duckworth Navigator Sport 195 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 255 2010 could be the deciding factor.
