Monterey 278SC 2010 vs Monterey 318SSX 2008 — Same Brand, Different Boat

Matching a modified vee Monterey 278SC 2010 against a deep vee Monterey 318SSX 2008 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.

On paper these two are close siblings in the size department — Monterey 278SC 2010 at 28,8 ft versus Monterey 318SSX 2008 at 31,0 ft. At 56 lbs and 8 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 425 hp, the Monterey 278SC 2010 has a 105-hp advantage over the Monterey 318SSX 2008'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 318SSX 2008 carries 142 gallons versus 89 gallons in the Monterey 278SC 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Monterey 318SSX 2008 at 31,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 278SC 2010 at 28,8 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 278SC 2010 vs Monterey 318SSX 2008 — Common Questions

Which is the larger boat — the Monterey 278SC 2010 or the Monterey 318SSX 2008?
The Monterey 318SSX 2008 is the longer of the two at 31,0 feet overall. The Monterey 278SC 2010 comes in at 28,8 feet, making it roughly 2,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 278SC 2010 or the Monterey 318SSX 2008?
For trailering, the Monterey 318SSX 2008 has the edge at 8 lbs dry weight versus 56 lbs for the Monterey 278SC 2010. 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 278SC 2010 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Monterey 318SSX 2008 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.
How many passengers can the Monterey 318SSX 2008 carry?
The Monterey 318SSX 2008 has an official capacity rating of 9 people. Capacity data wasn't available for the other model in this comparison — verify directly with the dealer.
Which boat is wider, and does it affect trailering?
The Monterey 318SSX 2008 measures 114" wide, compared to 102" for the Monterey 278SC 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.
Which boat has the larger fuel tank — the Monterey 278SC 2010 or the Monterey 318SSX 2008?
The Monterey 318SSX 2008 has the bigger tank at 142 gallons, versus 89 gallons on the Monterey 278SC 2010. That 53-gallon difference translates to roughly 159–265 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 278SC 2010 and Monterey 318SSX 2008 from the same manufacturer?
Yes — both the Monterey 278SC 2010 and the Monterey 318SSX 2008 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.
