Monterey 300SY 2013 vs Monterey 318SSX 2008: A Close Look at Two Deep-V Boats

Both the Monterey 300SY 2013 and the Monterey 318SSX 2008 are deep-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department - Monterey 300SY 2013 at 31,3 ft versus Monterey 318SSX 2008 at 31,0 ft. Weight tells a clearer story for trailering families: the Monterey 300SY 2013 tips the scales at 10 000 lbs - 2 000 lbs more than the Monterey 318SSX 2008 at 8 000 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 - 300 hp for the Monterey 300SY 2013 and 320 hp for the Monterey 318SSX 2008. 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. Both carry nearly identical fuel loads - 142 gal and 142 gal - so range won't be a tiebreaker here.

Bottom line: Performance buyers should lean toward the Monterey 318SSX 2008 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Monterey 300SY 2013 with its 300-hp rating is the more economical daily driver.

Monterey 300SY 2013 vs Monterey 318SSX 2008 - Common Questions

Which is the larger boat - the Monterey 300SY 2013 or the Monterey 318SSX 2008?
The Monterey 300SY 2013 is the longer of the two at 31,3 feet overall. The Monterey 318SSX 2008 comes in at 31,0 feet, making it roughly 0,3 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Monterey 300SY 2013 or the Monterey 318SSX 2008?
For trailering, the Monterey 318SSX 2008 has the edge at 8 000 lbs dry weight versus 10 000 lbs for the Monterey 300SY 2013. 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 318SSX 2008 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Monterey 300SY 2013 tops out at 300 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 300SY 2013 measures 123" wide, compared to 114" for the Monterey 318SSX 2008. 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.
How do the fuel tanks compare on the Monterey 300SY 2013 and Monterey 318SSX 2008?
Both boats carry similar fuel loads - 142 gallons and 142 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Monterey 300SY 2013 and Monterey 318SSX 2008 from the same manufacturer?
Yes - both the Monterey 300SY 2013 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.
