Both the Duckworth 255 2011 and the Duckworth Offshore 30 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 Offshore 30 2013 measures 32,0 feet overall (2013), giving it roughly 6,5 additional feet of deck space compared to the Duckworth 255 2011 at 25,5 feet (2011). Weight tells a clearer story for trailering families: the Duckworth Offshore 30 2013 tips the scales at 5 400 lbs - 2 680 lbs less than the Duckworth 255 2011 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 255 2011 and 500 hp for the Duckworth Offshore 30 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 Offshore 30 2013 carries 130 gallons versus 62 gallons in the Duckworth 255 2011. 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 Offshore 30 2013 is rated for 9 passengers, while the Duckworth 255 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 Offshore 30 2013 could be the deciding factor.
