Monterey 318SSX 2008 vs Monterey 385 SS 2020 — Same Brand, Different Boat

The Monterey 318SSX 2008 vs Monterey 385 SS 2020 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.

Size is the most obvious dividing line here. The Monterey 385 SS 2020 measures 37,0 feet overall (2020), giving it roughly 6,0 additional feet of deck space compared to the Monterey 318SSX 2008 at 31,0 feet (2008). Weight tells a clearer story for trailering families: the Monterey 385 SS 2020 tips the scales at 16 000 lbs — 15 992 lbs less than the Monterey 318SSX 2008 at 8 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.

The power gap is worth calling out. Rated to 400 hp, the Monterey 385 SS 2020 has a 80-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 25 gallons in the Monterey 385 SS 2020. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Monterey 385 SS 2020 is rated for 11 passengers, while the Monterey 318SSX 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Monterey 385 SS 2020 could be the deciding factor.

Bottom line: Choose the Monterey 385 SS 2020 if your priority is putting more people on the water — it handles 11 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Monterey 318SSX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Monterey 318SSX 2008 vs Monterey 385 SS 2020 — Common Questions

Which is the larger boat — the Monterey 318SSX 2008 or the Monterey 385 SS 2020?
The Monterey 385 SS 2020 is the longer of the two at 37,0 feet overall. The Monterey 318SSX 2008 comes in at 31,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 318SSX 2008 or the Monterey 385 SS 2020?
For trailering, the Monterey 318SSX 2008 has the edge at 8 lbs dry weight versus 16 000 lbs for the Monterey 385 SS 2020. 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 385 SS 2020 is rated to a maximum of 400 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 people can each boat hold?
The Monterey 318SSX 2008 is Coast Guard rated for 9 passengers, while the Monterey 385 SS 2020 is certified for 11. 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 385 SS 2020 measures 132" 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.
Which boat has the larger fuel tank — the Monterey 318SSX 2008 or the Monterey 385 SS 2020?
The Monterey 318SSX 2008 has the bigger tank at 142 gallons, versus 25 gallons on the Monterey 385 SS 2020. That 117-gallon difference translates to roughly 351–585 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 318SSX 2008 and Monterey 385 SS 2020 from the same manufacturer?
Yes — both the Monterey 318SSX 2008 and the Monterey 385 SS 2020 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.
