Detailed Evaluation & Buyer Recommendation

Duckworth Navigator Sport 175 2007 vs Duckworth Pro 721 2012: Same Brand, Different Boat

The Duckworth Navigator Sport 175 2007 is a deep-V design and the Duckworth Pro 721 2012 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.

For family outings this is probably the sharpest distinction between the two. The Duckworth Pro 721 2012 is rated for 6 passengers, while the Duckworth Navigator Sport 175 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Pro 721 2012 could be the deciding factor.

Bottom line: Choose the Duckworth Pro 721 2012 if your priority is putting more people on the water - it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Duckworth Navigator Sport 175 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
