Detailed Evaluation & Buyer Recommendation

Duckworth 30 2010 vs Duckworth Silverwing Inboard 21 ft. 2007: Same Brand, Different Boat

The Duckworth 30 2010 is a modified-V design and the Duckworth Silverwing Inboard 21 ft. 2007 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The Duckworth 30 2010 carries a rated maximum of 500 hp. Engine data for the Duckworth Silverwing Inboard 21 ft. 2007 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth 30 2010 carries 130 gallons versus 62 gallons in the Duckworth Silverwing Inboard 21 ft. 2007. 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 30 2010 is rated for 9 passengers, while the Duckworth Silverwing Inboard 21 ft. 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 30 2010 could be the deciding factor.

Bottom line: Choose the Duckworth 30 2010 if your priority is putting more people on the water - it handles 9 passengers and at 30,0 ft it has the deck room to back that rating up comfortably. The Duckworth Silverwing Inboard 21 ft. 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
