When two boats share the same hull type — in this case both the Duckworth 18 2010 and the Duckworth Pacific Silverwing 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 18 2010 carries a rated maximum of 115 hp. Engine data for the Duckworth Pacific Silverwing 20 ft. 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth Pacific Silverwing 20 ft. 2007 carries 62 gallons versus 42 gallons in the Duckworth 18 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Duckworth Pacific Silverwing 20 ft. 2007 is rated for 6 passengers, while the Duckworth 18 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Pacific Silverwing 20 ft. 2007 could be the deciding factor.
