When two boats share the same hull type — in this case both the Larson Cabrio 310 2008 and the Larson LX 950 I/O 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 11,6 additional feet of deck space compared to the Larson LX 950 I/O 2012 at 19,4 feet (2012). At 104 lbs and 27 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 298-hp advantage over the Larson LX 950 I/O 2012's 22-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson Cabrio 310 2008 carries 16 gallons versus 3 gallons in the Larson LX 950 I/O 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
