Monterey 318SC 2008 vs Monterey 328 SS 2019 — Same Brand, Different Boat

The Monterey 318SC 2008 vs Monterey 328 SS 2019 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Monterey 318SC 2008 at 31,0 ft versus Monterey 328 SS 2019 at 32,2 ft. Weight tells a clearer story for trailering families: the Monterey 328 SS 2019 tips the scales at 97 000 lbs — 96 915 lbs less than the Monterey 318SC 2008 at 85 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 — 320 hp for the Monterey 318SC 2008 and 300 hp for the Monterey 328 SS 2019. 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.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Monterey 318SC 2008 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Monterey 328 SS 2019 with its 300-hp rating is the more economical daily driver.

Monterey 318SC 2008 vs Monterey 328 SS 2019 — Common Questions

Which is the larger boat — the Monterey 318SC 2008 or the Monterey 328 SS 2019?
The Monterey 328 SS 2019 is the longer of the two at 32,2 feet overall. The Monterey 318SC 2008 comes in at 31,0 feet, making it roughly 1,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 318SC 2008 or the Monterey 328 SS 2019?
For trailering, the Monterey 318SC 2008 has the edge at 85 lbs dry weight versus 97 000 lbs for the Monterey 328 SS 2019. 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 318SC 2008 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Monterey 328 SS 2019 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 people can each boat hold?
The Monterey 318SC 2008 is Coast Guard rated for 9 passengers, while the Monterey 328 SS 2019 is certified for 9. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Monterey 328 SS 2019 measures 118" wide, compared to 114" for the Monterey 318SC 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 318SC 2008 and Monterey 328 SS 2019?
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 318SC 2008 and Monterey 328 SS 2019 from the same manufacturer?
Yes — both the Monterey 318SC 2008 and the Monterey 328 SS 2019 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.
