When two boats share the same hull type — in this case both the Duckworth 255 2011 and the Duckworth Offshore 28 2013 are deep vee designs with aluminum construction — 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 2011 measures 25,5 feet overall (2011), giving it roughly 22,5 additional feet of deck space compared to the Duckworth Offshore 28 2013 at 3,0 feet (2013). Weight tells a clearer story for trailering families: the Duckworth 255 2011 tips the scales at 272 lbs — 221 lbs more than the Duckworth Offshore 28 2013 at 51 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 28 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 255 2011 carries 62 gallons versus 13 gallons in the Duckworth Offshore 28 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 Offshore 28 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 28 2013 could be the deciding factor.
