Both the Duckworth 215SE 2011 and the Duckworth Ultra Magnum Inboard Jet 23 2012 are deep-V designs, both built in aluminium, so 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?
On paper these two are close siblings in the size department - Duckworth 215SE 2011 at 21,5 ft versus Duckworth Ultra Magnum Inboard Jet 23 2012 at 23,0 ft. Weight tells a clearer story for trailering families: the Duckworth Ultra Magnum Inboard Jet 23 2012 tips the scales at 3 610 lbs - 1 692 lbs less than the Duckworth 215SE 2011 at 1 918 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 215SE 2011 carries a rated maximum of 250 hp. Engine data for the Duckworth Ultra Magnum Inboard Jet 23 2012 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Duckworth Ultra Magnum Inboard Jet 23 2012 carries 80 gallons versus 62 gallons in the Duckworth 215SE 2011. 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 Ultra Magnum Inboard Jet 23 2012 is rated for 7 passengers, while the Duckworth 215SE 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 Ultra Magnum Inboard Jet 23 2012 could be the deciding factor.
Bottom line: Choose the Duckworth Ultra Magnum Inboard Jet 23 2012 if your priority is putting more people on the water - it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Duckworth 215SE 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
