When two boats share the same hull type — in this case both the Duckworth Pacific Navigator 255 2009 and the Duckworth Pacific Silverwing 21 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 Pacific Navigator 255 2009 carries a rated maximum of 500 hp. Engine data for the Duckworth Pacific Silverwing 21 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 Pacific Navigator 255 2009 is rated for 7 passengers, while the Duckworth Pacific Silverwing 21 ft. 2007 caps at 6.
