Monterey 235 SS 2020 vs Monterey M6 2019 — Same Brand, Different Boat

The Monterey 235 SS 2020 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.

On paper these two are close siblings in the size department — Monterey 235 SS 2020 at 23,5 ft versus Monterey M6 2019 at 25,1 ft. Weight tells a clearer story for trailering families: the Monterey M6 2019 tips the scales at 5 200 lbs — 1 550 lbs less than the Monterey 235 SS 2020 at 3 650 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 160-hp advantage over the Monterey 235 SS 2020's 300-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 235 SS 2020 carries 52 gallons versus 8 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.

Both boats are rated for 7 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 M6 2019 and its 460-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Monterey 235 SS 2020 with its 300-hp rating is the more economical daily driver.

Monterey 235 SS 2020 vs Monterey M6 2019 — Common Questions

Which is the larger boat — the Monterey 235 SS 2020 or the Monterey M6 2019?
The Monterey M6 2019 is the longer of the two at 25,1 feet overall. The Monterey 235 SS 2020 comes in at 23,5 feet, making it roughly 1,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 235 SS 2020 or the Monterey M6 2019?
For trailering, the Monterey 235 SS 2020 has the edge at 3 650 lbs dry weight versus 5 200 lbs for the Monterey M6 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 M6 2019 is rated to a maximum of 460 hp, giving it the larger power ceiling. The Monterey 235 SS 2020 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 235 SS 2020 is Coast Guard rated for 7 passengers, while the Monterey M6 2019 is certified for 7. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Monterey 235 SS 2020 and Monterey M6 2019 share an 8.60 ft beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Monterey 235 SS 2020 or the Monterey M6 2019?
The Monterey 235 SS 2020 has the bigger tank at 52 gallons, versus 8 gallons on the Monterey M6 2019. That 44-gallon difference translates to roughly 132–220 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 235 SS 2020 and Monterey M6 2019 from the same manufacturer?
Yes — both the Monterey 235 SS 2020 and the Monterey M6 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.
