Grady-White Advance 257 2009 vs Grady-White Marlin 300 2022 — Same Brand, Different Boat

The Grady-White Advance 257 2009 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 Advance 257 2009 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 Marlin 300 2022 carries 282 gallons versus 151 gallons in the Grady-White Advance 257 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 Marlin 300 2022 is rated for 9 passengers, while the Grady-White Advance 257 2009 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grady-White Marlin 300 2022 could be the deciding factor.

Bottom line: Choose the Grady-White Marlin 300 2022 if your priority is putting more people on the water — it handles 9 passengers and at 30,6 ft it has the deck room to back that rating up comfortably. The Grady-White Advance 257 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
