Duckworth 21 2011 vs Duckworth Pro 721 2012 — Same Brand, Different Boat

Matching a deep vee Duckworth 21 2011 against a modified vee Duckworth Pro 721 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Duckworth 21 2011 at 21,0 ft versus Duckworth Pro 721 2012 at 21,0 ft. At 28 lbs and 16 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.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Duckworth 21 2011 and Duckworth Pro 721 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Duckworth 21 2011 vs Duckworth Pro 721 2012 — Common Questions

Which is the larger boat — the Duckworth 21 2011 or the Duckworth Pro 721 2012?
The Duckworth Pro 721 2012 is the longer of the two at 21,0 feet overall. The Duckworth 21 2011 comes in at 21,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Duckworth 21 2011 or the Duckworth Pro 721 2012?
For trailering, the Duckworth Pro 721 2012 has the edge at 16 lbs dry weight versus 28 lbs for the Duckworth 21 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Duckworth 21 2011 is Coast Guard rated for 6 passengers, while the Duckworth Pro 721 2012 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Duckworth Pro 721 2012 measures 102" wide, compared to 94" for the Duckworth 21 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Duckworth 21 2011 or the Duckworth Pro 721 2012?
The Duckworth 21 2011 has the bigger tank at 62 gallons, versus 42 gallons on the Duckworth Pro 721 2012. That 20-gallon difference translates to roughly 60–100 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Duckworth 21 2011 and Duckworth Pro 721 2012 from the same manufacturer?
Yes — both the Duckworth 21 2011 and the Duckworth Pro 721 2012 are built by Duckworth. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
