The Monterey 255 SS 2020 vs Monterey 278SS 2009 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 255 SS 2020 at 25,8 ft versus Monterey 278SS 2009 at 28,0 ft. Weight tells a clearer story for trailering families: the Monterey 255 SS 2020 tips the scales at 5 500 lbs — 5 445 lbs more than the Monterey 278SS 2009 at 55 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 278SS 2009 has a 75-hp advantage over the Monterey 255 SS 2020's 350-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 278SS 2009 carries 89 gallons versus 65 gallons in the Monterey 255 SS 2020. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 255 SS 2020 is rated for up to 7 people. Passenger data for the Monterey 278SS 2009 wasn't available.
