Both the JC Manufacturing TriToon 246 I/O 2008 and the JC Manufacturing TriToon Classic 266 O/B 2010 are pontoon 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 - JC Manufacturing TriToon 246 I/O 2008 at 24,0 ft versus JC Manufacturing TriToon Classic 266 O/B 2010 at 26,0 ft. Weight tells a clearer story for trailering families: the JC Manufacturing TriToon 246 I/O 2008 tips the scales at 4 150 lbs - 950 lbs more than the JC Manufacturing TriToon Classic 266 O/B 2010 at 3 200 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 - 320 hp for the JC Manufacturing TriToon 246 I/O 2008 and 300 hp for the JC Manufacturing TriToon Classic 266 O/B 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 7 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 JC Manufacturing TriToon 246 I/O 2008 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the JC Manufacturing TriToon Classic 266 O/B 2010 with its 300-hp rating is the more economical daily driver.
