Detailed Evaluation & Buyer Recommendation
Monterey 400SY 2008 vs Monterey M5 2011 — Which Modified Vee Fits Your Needs?
When two boats share the same hull type — in this case both the Monterey 400SY 2008 and the Monterey M5 2011 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
The power gap is worth calling out. Rated to 425 hp, the Monterey M5 2011 has a 50-hp advantage over the Monterey 400SY 2008's 375-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 2008 carries 33 gallons versus 8 gallons in the Monterey M5 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
The Monterey 400SY 2008 is rated for up to 12 people. Passenger data for the Monterey M5 2011 wasn't available.
Bottom line: The Monterey 400SY 2008 at 41,0 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.
