Both the Grady-White Chase 273 2010 and the Grady-White Tournament 275 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?
On paper these two are close siblings in the size department - Grady-White Chase 273 2010 at 26,9 ft versus Grady-White Tournament 275 2010 at 26,9 ft. Weight tells a clearer story for trailering families: the Grady-White Tournament 275 2010 tips the scales at 4 972 lbs - 129 lbs less than the Grady-White Chase 273 2010 at 4 843 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 - 500 hp for the Grady-White Chase 273 2010 and 500 hp for the Grady-White Tournament 275 2010. 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 Grady-White Chase 273 2010 carries 205 gallons versus 200 gallons in the Grady-White Tournament 275 2010. 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.
Bottom line: The Grady-White Chase 273 2010 and Grady-White Tournament 275 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
