When two boats share the same hull type — in this case both the Duckworth 18 2011 and the Duckworth 23 2010 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 23 2010 measures 23,0 feet overall (2010), giving it roughly 5,0 additional feet of deck space compared to the Duckworth 18 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Duckworth 18 2011 tips the scales at 2 375 lbs — 2 014 lbs more than the Duckworth 23 2010 at 361 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 Duckworth 18 2011 carries a rated maximum of 115 hp. Engine data for the Duckworth 23 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth 18 2011 carries 42 gallons versus 8 gallons in the Duckworth 23 2010. 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 23 2010 is rated for 7 passengers, while the Duckworth 18 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 23 2010 could be the deciding factor.
Bottom line: Choose the Duckworth 23 2010 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Duckworth 18 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
