The Go-Devil 15 x 30 Duck Skiff 2005 vs Go-Devil 20 x 56 2011 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 15 x 30 Duck Skiff 2005 measures 15,0 feet overall (2005), giving it roughly 13,0 additional feet of deck space compared to the Go-Devil 20 x 56 2011 at 2,0 feet (2011). Weight tells a clearer story for trailering families: the Go-Devil 15 x 30 Duck Skiff 2005 tips the scales at 283 lbs — 221 lbs more than the Go-Devil 20 x 56 2011 at 62 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 2011 has a 35-hp advantage over the Go-Devil 15 x 30 Duck Skiff 2005'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 2011 is rated for 6 passengers, while the Go-Devil 15 x 30 Duck Skiff 2005 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 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Go-Devil 20 x 56 2011 comes in at 1 lbs per hp versus 19 lbs per hp for the Go-Devil 15 x 30 Duck Skiff 2005. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
