Grady-White Canyon 306 2022 vs Grady-White Canyon 366 2010 — Same Brand, Different Boat

The Grady-White Canyon 306 2022 vs Grady-White Canyon 366 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 1 050 hp, the Grady-White Canyon 366 2010 has a 750-hp advantage over the Grady-White Canyon 306 2022's 300-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 Canyon 366 2010 carries 42 gallons versus 29 gallons in the Grady-White Canyon 306 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Grady-White Canyon 366 2010 is rated for 11 passengers, while the Grady-White Canyon 306 2022 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grady-White Canyon 366 2010 could be the deciding factor.

Bottom line: Choose the Grady-White Canyon 366 2010 if your priority is putting more people on the water — it handles 11 passengers and at 36,6 ft it has the deck room to back that rating up comfortably. The Grady-White Canyon 306 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Grady-White Canyon 306 2022 vs Grady-White Canyon 366 2010 — Common Questions

The Grady-White Canyon 366 2010 is the longer of the two at 36,6 feet overall. The Grady-White Canyon 306 2022 comes in at 30,6 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Grady-White Canyon 366 2010 is rated to a maximum of 1 050 hp, giving it the larger power ceiling. The Grady-White Canyon 306 2022 tops out at 300 hp.

How many people can each boat hold?
The Grady-White Canyon 306 2022 is Coast Guard rated for 9 passengers, while the Grady-White Canyon 366 2010 is certified for 11. 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 Canyon 366 2010 measures 158" wide, compared to 128" for the Grady-White Canyon 306 2022. 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.

The Grady-White Canyon 366 2010 has the bigger tank at 42 gallons, versus 29 gallons on the Grady-White Canyon 306 2022. That 13-gallon difference translates to roughly 39–65 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

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.
