The Go-Devil 20 x 48 SD 2010 vs Go-Devil 20 x 60 SD - Standard 2005 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.
On paper these two are close siblings in the size department - Go-Devil 20 x 48 SD 2010 at 20,0 ft versus Go-Devil 20 x 60 SD - Standard 2005 at 20,0 ft. At 590 lbs and 660 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 40 hp for the Go-Devil 20 x 48 SD 2010 and 50 hp for the Go-Devil 20 x 60 SD - Standard 2005. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
Both boats are rated for 6 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Go-Devil 20 x 48 SD 2010 and Go-Devil 20 x 60 SD - Standard 2005 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
