When two boats share the same hull type — in this case both the Monterey 254FSX 2008 and the Monterey 330 SY 2008 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?
Size is the most obvious dividing line here. The Monterey 330 SY 2008 measures 35,0 feet overall (2008), giving it roughly 9,0 additional feet of deck space compared to the Monterey 254FSX 2008 at 26,0 feet (2008). At 52 lbs and 142 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 425 hp, the Monterey 254FSX 2008 has a 105-hp advantage over the Monterey 330 SY 2008's 320-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 330 SY 2008 carries 21 gallons versus 8 gallons in the Monterey 254FSX 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
The Monterey 254FSX 2008 is rated for up to 8 people. Passenger data for the Monterey 330 SY 2008 wasn't available.
Bottom line: The Monterey 330 SY 2008 at 35,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 254FSX 2008 at 26,0 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.
