When two boats share the same hull type — in this case both the Duckworth 175 2010 and the Duckworth 215 2011 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 215 2011 measures 21,5 feet overall (2011), giving it roughly 4,0 additional feet of deck space compared to the Duckworth 175 2010 at 17,5 feet (2010). At 142 lbs and 227 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 250 hp, the Duckworth 215 2011 has a 135-hp advantage over the Duckworth 175 2010's 115-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 215 2011 carries 62 gallons versus 42 gallons in the Duckworth 175 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 215 2011 is rated for 6 passengers, while the Duckworth 175 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 215 2011 could be the deciding factor.
Bottom line: Choose the Duckworth 215 2011 if your priority is putting more people on the water — it handles 6 passengers and at 21,5 ft it has the deck room to back that rating up comfortably. The Duckworth 175 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
