Monterey 318SSX 2009 vs Monterey 350 Sport Yacht 2006 — Same Brand, Different Boat

The Monterey 318SSX 2009 vs Monterey 350 Sport Yacht 2006 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 350 Sport Yacht 2006 measures 37,0 feet overall (2006), giving it roughly 6,0 additional feet of deck space compared to the Monterey 318SSX 2009 at 31,0 feet (2009). Weight tells a clearer story for trailering families: the Monterey 350 Sport Yacht 2006 tips the scales at 165 lbs — 157 lbs less than the Monterey 318SSX 2009 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 425 hp, the Monterey 350 Sport Yacht 2006 has a 105-hp advantage over the Monterey 318SSX 2009'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 2009 carries 142 gallons versus 23 gallons in the Monterey 350 Sport Yacht 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Monterey 350 Sport Yacht 2006 at 37,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 318SSX 2009 at 31,0 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 318SSX 2009 vs Monterey 350 Sport Yacht 2006 — Common Questions

Which is the larger boat — the Monterey 318SSX 2009 or the Monterey 350 Sport Yacht 2006?
The Monterey 350 Sport Yacht 2006 is the longer of the two at 37,0 feet overall. The Monterey 318SSX 2009 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 2009 or the Monterey 350 Sport Yacht 2006?
For trailering, the Monterey 318SSX 2009 has the edge at 8 lbs dry weight versus 165 lbs for the Monterey 350 Sport Yacht 2006. 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 350 Sport Yacht 2006 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Monterey 318SSX 2009 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.
Which boat is wider, and does it affect trailering?
The Monterey 350 Sport Yacht 2006 measures 138" wide, compared to 114" for the Monterey 318SSX 2009. 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 2009 or the Monterey 350 Sport Yacht 2006?
The Monterey 318SSX 2009 has the bigger tank at 142 gallons, versus 23 gallons on the Monterey 350 Sport Yacht 2006. That 119-gallon difference translates to roughly 357–595 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 318SSX 2009 and Monterey 350 Sport Yacht 2006 from the same manufacturer?
Yes — both the Monterey 318SSX 2009 and the Monterey 350 Sport Yacht 2006 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.
