Duckworth 21 2010 vs Duckworth 723 2011 — Same Brand, Different Boat

Matching a deep vee Duckworth 21 2010 against a modified vee Duckworth 723 2011 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 2010 at 21,0 ft versus Duckworth 723 2011 at 23,0 ft. At 28 lbs and 17 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.

For family outings this is probably the sharpest distinction between the two. The Duckworth 723 2011 is rated for 7 passengers, while the Duckworth 21 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 723 2011 could be the deciding factor.

Bottom line: Choose the Duckworth 723 2011 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 21 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Duckworth 21 2010 vs Duckworth 723 2011 — Common Questions

Which is the larger boat — the Duckworth 21 2010 or the Duckworth 723 2011?
The Duckworth 723 2011 is the longer of the two at 23,0 feet overall. The Duckworth 21 2010 comes in at 21,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Duckworth 21 2010 or the Duckworth 723 2011?
For trailering, the Duckworth 723 2011 has the edge at 17 lbs dry weight versus 28 lbs for the Duckworth 21 2010. 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 2010 is Coast Guard rated for 6 passengers, while the Duckworth 723 2011 is certified for 7. 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 723 2011 measures 102" wide, compared to 94" for the Duckworth 21 2010. 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 2010 or the Duckworth 723 2011?
The Duckworth 21 2010 has the bigger tank at 62 gallons, versus 42 gallons on the Duckworth 723 2011. 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 2010 and Duckworth 723 2011 from the same manufacturer?
Yes — both the Duckworth 21 2010 and the Duckworth 723 2011 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.
