Matching a modified vee Monterey 340SY 2009 against a deep vee Monterey M3 MSX 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.

Size is the most obvious dividing line here. The Monterey 340SY 2009 measures 35,0 feet overall (2009), giving it roughly 11,2 additional feet of deck space compared to the Monterey M3 MSX 2012 at 23,8 feet (2012). At 142 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.

The power gap is worth calling out. Rated to 375 hp, the Monterey 340SY 2009 has a 55-hp advantage over the Monterey M3 MSX 2012's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Monterey 340SY 2009 carries 21 gallons versus 5 gallons in the Monterey M3 MSX 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
