When two boats share the same hull type — in this case both the Chaparral 255 SSi Sportboat 2006 and the Chaparral SSi 246 2011 are modified vee designs with composite 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 — Chaparral 255 SSi Sportboat 2006 at 26,0 ft versus Chaparral SSi 246 2011 at 24,5 ft. Weight tells a clearer story for trailering families: the Chaparral 255 SSi Sportboat 2006 tips the scales at 554 lbs — 510 lbs more than the Chaparral SSi 246 2011 at 44 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 425 hp, the Chaparral 255 SSi Sportboat 2006 has a 105-hp advantage over the Chaparral SSi 246 2011's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Chaparral SSi 246 2011 carries 65 gallons versus 8 gallons in the Chaparral 255 SSi Sportboat 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
