When two boats share the same hull type — in this case both the Duckworth 20 2010 and the Duckworth Pacific Navigator 175 Sport 2009 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?

Size is the most obvious dividing line here. The Duckworth Pacific Navigator 175 Sport 2009 measures 17,5 feet overall (2009), giving it roughly 15,5 additional feet of deck space compared to the Duckworth 20 2010 at 2,0 feet (2010). Weight tells a clearer story for trailering families: the Duckworth Pacific Navigator 175 Sport 2009 tips the scales at 1 425 lbs — 1 398 lbs less than the Duckworth 20 2010 at 27 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Duckworth Pacific Navigator 175 Sport 2009 tops out at 115 hp. Engine specs for the Duckworth 20 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Duckworth 20 2010 carries 62 gallons versus 42 gallons in the Duckworth Pacific Navigator 175 Sport 2009. 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 20 2010 is rated for 6 passengers, while the Duckworth Pacific Navigator 175 Sport 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth 20 2010 could be the deciding factor.
