Monterey 228 SI Montura 2006 vs Monterey M-20 2019 — Same Brand, Different Boat

The Monterey 228 SI Montura 2006 vs Monterey M-20 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 228 SI Montura 2006 at 21,0 ft versus Monterey M-20 2019 at 22,2 ft. Weight tells a clearer story for trailering families: the Monterey M-20 2019 tips the scales at 3 500 lbs — 3 462 lbs less than the Monterey 228 SI Montura 2006 at 38 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 320 hp, the Monterey 228 SI Montura 2006 has a 40-hp advantage over the Monterey M-20 2019's 280-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 228 SI Montura 2006 carries 57 gallons versus 36 gallons in the Monterey M-20 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 6 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 228 SI Montura 2006 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Monterey M-20 2019 with its 280-hp rating is the more economical daily driver.

Monterey 228 SI Montura 2006 vs Monterey M-20 2019 — Common Questions

Which is the larger boat — the Monterey 228 SI Montura 2006 or the Monterey M-20 2019?
The Monterey M-20 2019 is the longer of the two at 22,2 feet overall. The Monterey 228 SI Montura 2006 comes in at 21,0 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 228 SI Montura 2006 or the Monterey M-20 2019?
For trailering, the Monterey 228 SI Montura 2006 has the edge at 38 lbs dry weight versus 3 500 lbs for the Monterey M-20 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 228 SI Montura 2006 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Monterey M-20 2019 tops out at 280 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 228 SI Montura 2006 is Coast Guard rated for 6 passengers, while the Monterey M-20 2019 is certified for 6. 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 228 SI Montura 2006 measures 102" wide, compared to 101" for the Monterey M-20 2019. 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 228 SI Montura 2006 or the Monterey M-20 2019?
The Monterey 228 SI Montura 2006 has the bigger tank at 57 gallons, versus 36 gallons on the Monterey M-20 2019. That 21-gallon difference translates to roughly 63–105 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 228 SI Montura 2006 and Monterey M-20 2019 from the same manufacturer?
Yes — both the Monterey 228 SI Montura 2006 and the Monterey M-20 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.
