Duckworth 23 2011 vs Duckworth 721 2011 - Boat Spec Comparison

Q: Which is the larger boat - the Duckworth 23 2011 or the Duckworth 721 2011?

The Duckworth 23 2011 is the longer of the two at 23,0 feet overall. The Duckworth 721 2011 comes in at 21,0 feet, making it roughly 2,0 ft shorter - a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer - the Duckworth 23 2011 or the Duckworth 721 2011?

For trailering, the Duckworth 721 2011 has the edge at 1 600 lbs dry weight versus 3 610 lbs for the Duckworth 23 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.

Q: How many people can each boat hold?

The Duckworth 23 2011 is Coast Guard rated for 7 passengers, while the Duckworth 721 2011 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.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Duckworth 23 2011 and Duckworth 721 2011 share an 102 in. beam - meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank - the Duckworth 23 2011 or the Duckworth 721 2011?

The Duckworth 23 2011 has the bigger tank at 80 gallons, versus 42 gallons on the Duckworth 721 2011. That 38-gallon difference translates to roughly 114–190 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Duckworth 23 2011 and Duckworth 721 2011 from the same manufacturer?

Yes - both the Duckworth 23 2011 and the Duckworth 721 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.

Detailed Evaluation & Buyer Recommendation

Duckworth 23 2011 vs Duckworth 721 2011: Same Brand, Different Boat

The Duckworth 23 2011 is a deep-V design and the Duckworth 721 2011 is a modified-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.

On paper these two are close siblings in the size department - Duckworth 23 2011 at 23,0 ft versus Duckworth 721 2011 at 21,0 ft. Weight tells a clearer story for trailering families: the Duckworth 23 2011 tips the scales at 3 610 lbs - 2 010 lbs more than the Duckworth 721 2011 at 1 600 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.

For family outings this is probably the sharpest distinction between the two. The Duckworth 23 2011 is rated for 7 passengers, while the Duckworth 721 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 23 2011 could be the deciding factor.

Bottom line: Choose the Duckworth 23 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 721 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
