Both the Go-Devil 18 x 38 2013 and the Go-Devil 18 x 60 SD 2010 are flat-bottom 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 - Go-Devil 18 x 38 2013 at 18,0 ft versus Go-Devil 18 x 60 SD 2010 at 18,0 ft. Weight tells a clearer story for trailering families: the Go-Devil 18 x 60 SD 2010 tips the scales at 620 lbs - 190 lbs less than the Go-Devil 18 x 38 2013 at 430 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.
Both boats share a closely matched power ceiling - 30 hp for the Go-Devil 18 x 38 2013 and 45 hp for the Go-Devil 18 x 60 SD 2010. 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 5 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Go-Devil 18 x 60 SD 2010 comes in at 14 lbs per hp versus 14 lbs per hp for the Go-Devil 18 x 38 2013. 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.
Bottom line: The Go-Devil 18 x 38 2013 and Go-Devil 18 x 60 SD 2010 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.
