When two boats share the same hull type — in this case both the Larson 310 Cabrio 2010 and the Larson Cabrio 220 2009 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 310 Cabrio 2010 measures 31,0 feet overall (2010), giving it roughly 9,0 additional feet of deck space compared to the Larson Cabrio 220 2009 at 22,0 feet (2009). At 104 lbs and 42 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 Larson 310 Cabrio 2010 carries a rated maximum of 320 hp. Engine data for the Larson Cabrio 220 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson 310 Cabrio 2010 carries 16 gallons versus 6 gallons in the Larson Cabrio 220 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
