The Chaparral 276 SSi Sportboat 2006 is a modified-V design and the Chaparral Signature 270 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Chaparral 276 SSi Sportboat 2006 at 28,0 ft versus Chaparral Signature 270 2013 at 27,0 ft. Weight tells a clearer story for trailering families: the Chaparral Signature 270 2013 tips the scales at 6 900 lbs - 105 lbs less than the Chaparral 276 SSi Sportboat 2006 at 6 795 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 276 SSi Sportboat 2006 has a 45-hp advantage over the Chaparral Signature 270 2013's 380-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 276 SSi Sportboat 2006 carries 105 gallons versus 79 gallons in the Chaparral Signature 270 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Chaparral 276 SSi Sportboat 2006 is rated for up to 8 people. Passenger data for the Chaparral Signature 270 2013 wasn't available.
