The Monterey 350 SY 2008 is a modified-V design and the Monterey 400SY 2012 is a deep-V design, so you're likely deciding between two noticeably 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 400SY 2012 measures 41,0 feet overall (2012), giving it roughly 4,0 additional feet of deck space compared to the Monterey 350 SY 2008 at 37,0 feet (2008). Weight tells a clearer story for trailering families: the Monterey 400SY 2012 tips the scales at 22 000 lbs - 5 500 lbs less than the Monterey 350 SY 2008 at 16 500 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling - 425 hp for the Monterey 350 SY 2008 and 435 hp for the Monterey 400SY 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 400SY 2012 carries 330 gallons versus 230 gallons in the Monterey 350 SY 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
