When two boats share the same hull type — in this case both the Duckworth Magnum Inboard 23 ft. 2007 and the Duckworth Navigator Sport 20 2012 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 Navigator Sport 20 2012 tops out at 15 hp. Engine specs for the Duckworth Magnum Inboard 23 ft. 2007 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Duckworth Navigator Sport 20 2012 carries 42 gallons versus 8 gallons in the Duckworth Magnum Inboard 23 ft. 2007. 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 Magnum Inboard 23 ft. 2007 is rated for 7 passengers, while the Duckworth Navigator Sport 20 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Magnum Inboard 23 ft. 2007 could be the deciding factor.
