Detailed Evaluation & Buyer Recommendation
Monterey 318SS 2009 vs Monterey M3 2011 — Same Brand, Different Boat
Matching a deep vee Monterey 318SS 2009 against a modified vee Monterey M3 2011 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.
Size is the most obvious dividing line here. The Monterey 318SS 2009 measures 31,0 feet overall (2009), giving it roughly 7,2 additional feet of deck space compared to the Monterey M3 2011 at 23,8 feet (2011). At 8 lbs and 45 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 320 hp for the Monterey 318SS 2009 and 320 hp for the Monterey M3 2011. 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 318SS 2009 carries 142 gallons versus 5 gallons in the Monterey M3 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Monterey 318SS 2009 at 31,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey M3 2011 at 23,8 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
