When two boats share the same hull type — in this case both the ProKat 2660 Walk Around 2007 and the ProKat 2860 Walk Around 2008 are catamaran designs with fiberglass construction — 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 — ProKat 2660 Walk Around 2007 at 27,0 ft versus ProKat 2860 Walk Around 2008 at 29,0 ft. Weight tells a clearer story for trailering families: the ProKat 2860 Walk Around 2008 tips the scales at 525 lbs — 474 lbs less than the ProKat 2660 Walk Around 2007 at 51 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 500 hp, the ProKat 2860 Walk Around 2008 has a 50-hp advantage over the ProKat 2660 Walk Around 2007's 450-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 252 gal and 252 gal — so range won't be a tiebreaker here.
Both boats are rated for 8 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: Performance buyers should lean toward the ProKat 2860 Walk Around 2008 and its 500-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ProKat 2660 Walk Around 2007 with its 450-hp rating is the more economical daily driver.
