When two boats share the same hull type — in this case both the Monterey 234FSX 2010 and the Monterey M5 2010 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?

On paper these two are close siblings in the size department — Monterey 234FSX 2010 at 24,0 ft versus Monterey M5 2010 at 25,8 ft. At 43 lbs and 52 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 M5 2010 has a 105-hp advantage over the Monterey 234FSX 2010'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 234FSX 2010 carries 62 gallons versus 8 gallons in the Monterey M5 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Monterey M5 2010 is rated for 12 passengers, while the Monterey 234FSX 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Monterey M5 2010 could be the deciding factor.
