Detailed Evaluation & Buyer Recommendation
Duckworth 235 2011 vs Duckworth Silverwing Inboard 20 ft. 2007 — Which Deep Vee Fits Your Needs?
When two boats share the same hull type — in this case both the Duckworth 235 2011 and the Duckworth Silverwing Inboard 20 ft. 2007 are deep vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
The Duckworth 235 2011 carries a rated maximum of 450 hp. Engine data for the Duckworth Silverwing Inboard 20 ft. 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 62 gal and 62 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Duckworth 235 2011 is rated for 7 passengers, while the Duckworth Silverwing Inboard 20 ft. 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 235 2011 could be the deciding factor.
Bottom line: Choose the Duckworth 235 2011 if your priority is putting more people on the water — it handles 7 passengers and at 23,5 ft it has the deck room to back that rating up comfortably. The Duckworth Silverwing Inboard 20 ft. 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
