Monterey 320SY 2009 vs Monterey 400SY 2012 - Boat Spec Comparison

Q: Which is the larger boat — the Monterey 320SY 2009 or the Monterey 400SY 2012?

The Monterey 400SY 2012 is the longer of the two at 41,0 feet overall. The Monterey 320SY 2009 comes in at 33,0 feet, making it roughly 8,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Monterey 400SY 2012 is rated to a maximum of 435 hp, giving it the larger power ceiling. The Monterey 320SY 2009 tops out at 320 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.

Q: Which boat is wider, and does it affect trailering?

The Monterey 400SY 2012 measures 15" wide, compared to 13" for the Monterey 320SY 2009. 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.

Q: Which boat has the larger fuel tank — the Monterey 320SY 2009 or the Monterey 400SY 2012?

The Monterey 400SY 2012 has the bigger tank at 33 gallons, versus 18 gallons on the Monterey 320SY 2009. That 15-gallon difference translates to roughly 45–75 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Monterey 320SY 2009 and Monterey 400SY 2012 from the same manufacturer?

Yes — both the Monterey 320SY 2009 and the Monterey 400SY 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.

Detailed Evaluation & Buyer Recommendation

Monterey 320SY 2009 vs Monterey 400SY 2012 — Same Brand, Different Boat

Matching a modified vee Monterey 320SY 2009 against a deep vee Monterey 400SY 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.

The power gap is worth calling out. Rated to 435 hp, the Monterey 400SY 2012 has a 115-hp advantage over the Monterey 320SY 2009'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 400SY 2012 carries 33 gallons versus 18 gallons in the Monterey 320SY 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Monterey 400SY 2012 at 41,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 320SY 2009 at 33,0 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.
