When two boats share the same hull type — in this case both the Duckworth 24 2011 and the Duckworth Offshore 30 2012 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 Offshore 30 2012 measures 32,0 feet overall (2012), giving it roughly 8,0 additional feet of deck space compared to the Duckworth 24 2011 at 24,0 feet (2011). Weight tells a clearer story for trailering families: the Duckworth 24 2011 tips the scales at 372 lbs — 318 lbs more than the Duckworth Offshore 30 2012 at 54 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 450 hp, the Duckworth 24 2011 has a 445-hp advantage over the Duckworth Offshore 30 2012's 5-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 Offshore 30 2012 carries 175 gallons versus 8 gallons in the Duckworth 24 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 2012 is rated for 9 passengers, while the Duckworth 24 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 2012 could be the deciding factor.
