Matching a modified vee Monterey 320SY 2009 against a deep vee Monterey M3 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Both boats share a closely matched power ceiling — 320 hp for the Monterey 320SY 2009 and 320 hp for the Monterey M3 2012. 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 Monterey 320SY 2009 carries 18 gallons versus 5 gallons in the Monterey M3 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
