Monterey 318SC 2008 vs Monterey M6 2019: Same Brand, Different Boat
The Monterey 318SC 2008 vs Monterey M6 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.
Size is the most obvious dividing line here. The Monterey 318SC 2008 measures 31,0 feet overall (2008), giving it roughly 5,9 additional feet of deck space compared to the Monterey M6 2019 at 25,1 feet (2019). Weight tells a clearer story for trailering families: the Monterey 318SC 2008 tips the scales at 8 500 lbs - 3 300 lbs more than the Monterey M6 2019 at 5 200 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 460 hp, the Monterey M6 2019 has a 140-hp advantage over the Monterey 318SC 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 318SC 2008 carries 142 gallons versus 80 gallons in the Monterey M6 2019. 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 318SC 2008 is rated for 9 passengers, while the Monterey M6 2019 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Monterey 318SC 2008 could be the deciding factor.
Bottom line: Choose the Monterey 318SC 2008 if your priority is putting more people on the water - it handles 9 passengers and at 31,0 ft it has the deck room to back that rating up comfortably. The Monterey M6 2019 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
