When two boats share the same hull type — in this case both the Monterey 320SY 2010 and the Monterey 340SY 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 375 hp, the Monterey 340SY 2011 has a 55-hp advantage over the Monterey 320SY 2010's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 18 gal and 21 gal — so range won't be a tiebreaker here.
