Detailed Evaluation & Buyer Recommendation
Monterey 235 SS 2020 vs Monterey 400SY 2009: Same Brand, Different Boat
The Monterey 235 SS 2020 vs Monterey 400SY 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.
Size is the most obvious dividing line here. The Monterey 400SY 2009 measures 41,0 feet overall (2009), giving it roughly 17,5 additional feet of deck space compared to the Monterey 235 SS 2020 at 23,5 feet (2020). Weight tells a clearer story for trailering families: the Monterey 400SY 2009 tips the scales at 22 000 lbs - 18 350 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 435 hp, the Monterey 400SY 2009 has a 135-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 400SY 2009 carries 330 gallons versus 52 gallons in the Monterey 235 SS 2020. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
The Monterey 235 SS 2020 is rated for up to 7 people. Passenger data for the Monterey 400SY 2009 wasn't available.
Bottom line: The Monterey 400SY 2009 at 41,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 235 SS 2020 at 23,5 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.
