When two boats share the same hull type — in this case both the Chaparral 246 SSi Sportboat 2007 and the Chaparral 350 Signature Cruiser 2007 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 350 Signature Cruiser 2007 measures 37,0 feet overall (2007), giving it roughly 13,0 additional feet of deck space compared to the Chaparral 246 SSi Sportboat 2007 at 24,0 feet (2007). Weight tells a clearer story for trailering families: the Chaparral 246 SSi Sportboat 2007 tips the scales at 475 lbs — 460 lbs more than the Chaparral 350 Signature Cruiser 2007 at 15 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 — 375 hp for the Chaparral 246 SSi Sportboat 2007 and 375 hp for the Chaparral 350 Signature Cruiser 2007. 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. Fuel capacity breaks the other way: the Chaparral 246 SSi Sportboat 2007 carries 72 gallons versus 24 gallons in the Chaparral 350 Signature Cruiser 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Chaparral 246 SSi Sportboat 2007 is rated for up to 12 people. Passenger data for the Chaparral 350 Signature Cruiser 2007 wasn't available.
