Size is the most obvious dividing line here. The Go-Devil 20 x 48 SD 2006 measures 20,0 feet overall (2006), giving it roughly 6,0 additional feet of deck space compared to the Go-Devil Duck Boat 2005 at 14,0 feet (2005). Weight tells a clearer story for trailering families: the Go-Devil 20 x 48 SD 2006 tips the scales at 590 lbs - 490 lbs more than the Go-Devil Duck Boat 2005 at 100 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 Go-Devil 20 x 48 SD 2006 carries a rated maximum of 40 hp. Engine data for the Go-Devil Duck Boat 2005 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Go-Devil 20 x 48 SD 2006 could be the deciding factor.
Bottom line: Choose the Go-Devil 20 x 48 SD 2006 if your priority is putting more people on the water - it handles 6 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Go-Devil Duck Boat 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
