Both the Chaparral SSi 180 2009 and the Chaparral Sunesta 264 2010 are modified-V designs, both built in fibreglass, 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?

Size is the most obvious dividing line here. The Chaparral Sunesta 264 2010 measures 26,3 feet overall (2010), giving it roughly 8,3 additional feet of deck space compared to the Chaparral SSi 180 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the Chaparral Sunesta 264 2010 tips the scales at 5 400 lbs - 3 300 lbs less than the Chaparral SSi 180 2009 at 2 100 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 400 hp, the Chaparral Sunesta 264 2010 has a 210-hp advantage over the Chaparral SSi 180 2009's 190-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 Sunesta 264 2010 carries 80 gallons versus 23 gallons in the Chaparral SSi 180 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.
