When two boats share the same hull type — in this case both the Larson Cabrio 315 2013 and the Larson Cabrio 777 2012 are deep vee designs with composite 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 315 2013 measures 30,4 feet overall (2013), giving it roughly 4,9 additional feet of deck space compared to the Larson Cabrio 777 2012 at 25,5 feet (2012). Weight tells a clearer story for trailering families: the Larson Cabrio 777 2012 tips the scales at 585 lbs — 584 lbs less than the Larson Cabrio 315 2013 at 1 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.

The Larson Cabrio 777 2012 tops out at 26 hp. Engine specs for the Larson Cabrio 315 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Larson Cabrio 315 2013 carries 109 gallons versus 84 gallons in the Larson Cabrio 777 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Larson Cabrio 315 2013 is rated for 9 passengers, while the Larson Cabrio 777 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Cabrio 315 2013 could be the deciding factor.
