Grady-White Canyon 366 2009 vs Grady-White Seafarer 228 2007 — Same Brand, Different Boat

The Grady-White Canyon 366 2009 vs Grady-White Seafarer 228 2007 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 2009 has a 800-hp advantage over the Grady-White Seafarer 228 2007's 250-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 Seafarer 228 2007 carries 92 gallons versus 42 gallons in the Grady-White Canyon 366 2009. 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 2009 is rated for 11 passengers, while the Grady-White Seafarer 228 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grady-White Canyon 366 2009 could be the deciding factor.

Bottom line: Choose the Grady-White Canyon 366 2009 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 Seafarer 228 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
