Both the Larson 370 DC Cabrio 2010 and the Larson Cabrio 310 2009 are modified-V designs, both built in fibreglass, so 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 370 DC Cabrio 2010 measures 36,9 feet overall (2010), giving it roughly 5,9 additional feet of deck space compared to the Larson Cabrio 310 2009 at 31,0 feet (2009). Weight tells a clearer story for trailering families: the Larson 370 DC Cabrio 2010 tips the scales at 16 800 lbs - 6 400 lbs more than the Larson Cabrio 310 2009 at 10 400 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
