The Grady-White Canyon 336 2022 vs Grady-White Marlin 300 2022 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.
Both boats share a closely matched power ceiling — 350 hp for the Grady-White Canyon 336 2022 and 350 hp for the Grady-White Marlin 300 2022. 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 Canyon 336 2022 carries 361 gallons versus 282 gallons in the Grady-White Marlin 300 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 336 2022 is rated for 10 passengers, while the Grady-White Marlin 300 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 336 2022 could be the deciding factor.
Bottom line: Choose the Grady-White Canyon 336 2022 if your priority is putting more people on the water — it handles 10 passengers and at 33,6 ft it has the deck room to back that rating up comfortably. The Grady-White Marlin 300 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.
