Monterey 320SY 2010 vs Monterey 340SY 2012 - Boat Spec Comparison

Q: Which is the larger boat — the Monterey 320SY 2010 or the Monterey 340SY 2012?

The Monterey 340SY 2012 is the longer of the two at 35,3 feet overall. The Monterey 320SY 2010 comes in at 33,8 feet, making it roughly 1,4 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Monterey 340SY 2012 is rated to a maximum of 400 hp, giving it the larger power ceiling. The Monterey 320SY 2010 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 340SY 2012 measures 135" wide, compared to 13" for the Monterey 320SY 2010. 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 2010 or the Monterey 340SY 2012?

The Monterey 340SY 2012 has the bigger tank at 21 gallons, versus 18 gallons on the Monterey 320SY 2010. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Monterey 320SY 2010 and Monterey 340SY 2012 from the same manufacturer?

Yes — both the Monterey 320SY 2010 and the Monterey 340SY 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 2010 vs Monterey 340SY 2012 — Same Brand, Different Boat

Matching a modified vee Monterey 320SY 2010 against a deep vee Monterey 340SY 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 400 hp, the Monterey 340SY 2012 has a 80-hp advantage over the Monterey 320SY 2010's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 18 gal and 21 gal — so range won't be a tiebreaker here.

Bottom line: Performance buyers should lean toward the Monterey 340SY 2012 and its 400-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Monterey 320SY 2010 with its 320-hp rating is the more economical daily driver.
