When two boats share the same hull type — in this case both the Larson Cabrio 310 2008 and the Larson LX 620 SF O/B 2012 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 Larson Cabrio 310 2008 measures 31,0 feet overall (2008), giving it roughly 14,8 additional feet of deck space compared to the Larson LX 620 SF O/B 2012 at 16,2 feet (2012). At 104 lbs and 115 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 320 hp, the Larson Cabrio 310 2008 has a 230-hp advantage over the Larson LX 620 SF O/B 2012's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 16 gal and 19 gal — so range won't be a tiebreaker here.
