Monterey 400SY 2011 vs Monterey M5 2012 — Same Brand, Different Boat

Matching a modified vee Monterey 400SY 2011 against a deep vee Monterey M5 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 400SY 2011 measures 41,0 feet overall (2011), giving it roughly 15,2 additional feet of deck space compared to the Monterey M5 2012 at 25,8 feet (2012). At 22 lbs and 52 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 — 435 hp for the Monterey 400SY 2011 and 425 hp for the Monterey M5 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 2011 carries 33 gallons versus 8 gallons in the Monterey M5 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Monterey 400SY 2011 at 41,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey M5 2012 at 25,8 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.

Monterey 400SY 2011 vs Monterey M5 2012 — Common Questions

Which is the larger boat — the Monterey 400SY 2011 or the Monterey M5 2012?
The Monterey 400SY 2011 is the longer of the two at 41,0 feet overall. The Monterey M5 2012 comes in at 25,8 feet, making it roughly 15,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 400SY 2011 or the Monterey M5 2012?
For trailering, the Monterey 400SY 2011 has the edge at 22 lbs dry weight versus 52 lbs for the Monterey M5 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Monterey 400SY 2011 is rated to a maximum of 435 hp, giving it the larger power ceiling. The Monterey M5 2012 tops out at 425 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
Which boat is wider, and does it affect trailering?
The Monterey M5 2012 measures 102" wide, compared to 15" for the Monterey 400SY 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Monterey 400SY 2011 or the Monterey M5 2012?
The Monterey 400SY 2011 has the bigger tank at 33 gallons, versus 8 gallons on the Monterey M5 2012. That 25-gallon difference translates to roughly 75–125 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 400SY 2011 and Monterey M5 2012 from the same manufacturer?
Yes — both the Monterey 400SY 2011 and the Monterey M5 2012 are built by Monterey. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
