Grady-White Marlin 300 2022 vs Grady-White Tournament 307 2010 — Same Brand, Different Boat

The Grady-White Marlin 300 2022 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.

The power gap is worth calling out. Rated to 700 hp, the Grady-White Tournament 307 2010 has a 350-hp advantage over the Grady-White Marlin 300 2022's 350-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Grady-White Marlin 300 2022 carries 282 gallons versus 206 gallons in the Grady-White Tournament 307 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 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: Performance buyers should lean toward the Grady-White Tournament 307 2010 and its 700-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Grady-White Marlin 300 2022 with its 350-hp rating is the more economical daily driver.

Grady-White Marlin 300 2022 vs Grady-White Tournament 307 2010 — Common Questions

Which is the larger boat — the Grady-White Marlin 300 2022 or the Grady-White Tournament 307 2010?
The Grady-White Marlin 300 2022 is the longer of the two at 30,6 feet overall. The Grady-White Tournament 307 2010 comes in at 30,4 feet, making it roughly 0,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Grady-White Tournament 307 2010 is rated to a maximum of 700 hp, giving it the larger power ceiling. The Grady-White Marlin 300 2022 tops out at 350 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Grady-White Marlin 300 2022 is Coast Guard rated for 9 passengers, while the Grady-White Tournament 307 2010 is certified for 9. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Grady-White Marlin 300 2022 measures 128" wide, compared to 127" for the Grady-White Tournament 307 2010. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Grady-White Marlin 300 2022 or the Grady-White Tournament 307 2010?
The Grady-White Marlin 300 2022 has the bigger tank at 282 gallons, versus 206 gallons on the Grady-White Tournament 307 2010. That 76-gallon difference translates to roughly 228–380 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Grady-White Marlin 300 2022 and Grady-White Tournament 307 2010 from the same manufacturer?
Yes — both the Grady-White Marlin 300 2022 and the Grady-White Tournament 307 2010 are built by Grady-White. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
