Chaparral 280 SSi Sportboat 2004 vs Chaparral Signature 370 2010: Same Brand, Different Boat

The Chaparral 280 SSi Sportboat 2004 is a modified-V design and the Chaparral Signature 370 2010 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.

The power gap is worth calling out. Rated to 400 hp, the Chaparral Signature 370 2010 has a 80-hp advantage over the Chaparral 280 SSi Sportboat 2004'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 Signature 370 2010 carries 240 gallons versus 143 gallons in the Chaparral 280 SSi Sportboat 2004. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Chaparral 280 SSi Sportboat 2004 is rated for up to 8 people. Passenger data for the Chaparral Signature 370 2010 wasn't available.

Bottom line: Performance buyers should lean toward the Chaparral Signature 370 2010 and its 400-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Chaparral 280 SSi Sportboat 2004 with its 320-hp rating is the more economical daily driver.

For trailering, the Chaparral 280 SSi Sportboat 2004 has the edge at 6 800 lbs dry weight versus 16 500 lbs for the Chaparral Signature 370 2010.

The Chaparral Signature 370 2010 is rated to a maximum of 400 hp, giving it the larger power ceiling. The Chaparral 280 SSi Sportboat 2004 tops out at 320 hp.
