Detailed Evaluation & Buyer Recommendation
Monterey 378 SS 2020 vs Monterey M5 2011 — Same Brand, Different Boat
The Monterey 378 SS 2020 vs Monterey M5 2011 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 378 SS 2020 measures 37,0 feet overall (2020), giving it roughly 11,2 additional feet of deck space compared to the Monterey M5 2011 at 25,8 feet (2011). Weight tells a clearer story for trailering families: the Monterey 378 SS 2020 tips the scales at 16 000 lbs — 15 948 lbs more than the Monterey M5 2011 at 52 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 500 hp, the Monterey 378 SS 2020 has a 75-hp advantage over the Monterey M5 2011's 425-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 M5 2011 carries 8 gallons versus 2 gallons in the Monterey 378 SS 2020. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
The Monterey 378 SS 2020 is rated for up to 11 people. Passenger data for the Monterey M5 2011 wasn't available.
Bottom line: The Monterey 378 SS 2020 at 37,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey M5 2011 at 25,8 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.
