The Duckworth 21 2011 is a deep-V design and the Duckworth Pro 721 2013 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 21 2011 at 21,0 ft versus Duckworth Pro 721 2013 at 21,0 ft. Weight tells a clearer story for trailering families: the Duckworth 21 2011 tips the scales at 2 800 lbs - 1 200 lbs more than the Duckworth Pro 721 2013 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.

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.
