When two boats share the same hull type — in this case both the Chaparral SSi 204 2009 and the Chaparral Sunesta 264 2009 are modified vee 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?

Size is the most obvious dividing line here. The Chaparral Sunesta 264 2009 measures 26,0 feet overall (2009), giving it roughly 7,0 additional feet of deck space compared to the Chaparral SSi 204 2009 at 19,0 feet (2009). Weight tells a clearer story for trailering families: the Chaparral SSi 204 2009 tips the scales at 343 lbs — 289 lbs more than the Chaparral Sunesta 264 2009 at 54 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 Sunesta 264 2009 has a 125-hp advantage over the Chaparral SSi 204 2009's 300-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 204 2009 carries 51 gallons versus 8 gallons in the Chaparral Sunesta 264 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Chaparral SSi 204 2009 is rated for up to 1 people. Passenger data for the Chaparral Sunesta 264 2009 wasn't available.
