When two boats share the same hull type — in this case both the Duckworth 18 Sport 2011 and the Duckworth Magnum Inboard 22 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 Sport 2011 carries a rated maximum of 115 hp. Engine data for the Duckworth Magnum Inboard 22 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 Magnum Inboard 22 ft. 2007 carries 62 gallons versus 42 gallons in the Duckworth 18 Sport 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
