Duckworth 721 2011 vs Duckworth Boats Pro-steel-completely modified 1986 — Same Brand, Different Boat

The Duckworth 721 2011 vs Duckworth Boats Pro-steel-completely modified 1986 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The Duckworth Boats Pro-steel-completely modified 1986 tops out at 70 hp. Engine specs for the Duckworth 721 2011 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Duckworth 721 2011 is rated for 6 passengers, while the Duckworth Boats Pro-steel-completely modified 1986 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 721 2011 could be the deciding factor.

Bottom line: Choose the Duckworth 721 2011 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 Boats Pro-steel-completely modified 1986 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
