When two boats share the same hull type — in this case both the Duckworth 18 Sport 2011 and the Duckworth Pacific Magnum 23 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 Pacific Magnum 23 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 18 Sport 2011 carries 42 gallons versus 8 gallons in the Duckworth Pacific Magnum 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 Pacific Magnum 23 ft. 2007 is rated for 7 passengers, while the Duckworth 18 Sport 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Duckworth Pacific Magnum 23 ft. 2007 could be the deciding factor.
