The Go-Devil 15 x 36 Duck Skiff 2006 vs Go-Devil 20 x 56 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Go-Devil 20 x 56 2006 measures 20,0 feet overall (2006), giving it roughly 5,0 additional feet of deck space compared to the Go-Devil 15 x 36 Duck Skiff 2006 at 15,0 feet (2006). Weight tells a clearer story for trailering families: the Go-Devil 20 x 56 2006 tips the scales at 620 lbs - 295 lbs less than the Go-Devil 15 x 36 Duck Skiff 2006 at 325 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 power gap is worth calling out. Rated to 50 hp, the Go-Devil 20 x 56 2006 has a 35-hp advantage over the Go-Devil 15 x 36 Duck Skiff 2006's 15-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Go-Devil 20 x 56 2006 is rated for 6 passengers, while the Go-Devil 15 x 36 Duck Skiff 2006 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Go-Devil 20 x 56 2006 could be the deciding factor.
Bottom line: Choose the Go-Devil 20 x 56 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 15 x 36 Duck Skiff 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
