The Grady-White Express 305 2008 vs Grady-White Tournament 307 2010 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Grady-White Tournament 307 2010 measures 30,4 feet overall (2010), giving it roughly 27,4 additional feet of deck space compared to the Grady-White Express 305 2008 at 3,0 feet (2008). At 885 lbs and 785 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 700 hp for the Grady-White Express 305 2008 and 700 hp for the Grady-White Tournament 307 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 Tournament 307 2010 carries 206 gallons versus 29 gallons in the Grady-White Express 305 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 9 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 Tournament 307 2010 at 30,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Grady-White Express 305 2008 at 3,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
