Both the Larson Cabrio 310 2011 and the Larson FX 2050 DC O/B 2013 are deep-V designs, the first built in fibreglass and the second in composite, 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 Cabrio 310 2011 measures 31,0 feet overall (2011), giving it roughly 10,8 additional feet of deck space compared to the Larson FX 2050 DC O/B 2013 at 20,2 feet (2013). Weight tells a clearer story for trailering families: the Larson Cabrio 310 2011 tips the scales at 10 400 lbs - 7 632 lbs more than the Larson FX 2050 DC O/B 2013 at 2 768 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 power gap is worth calling out. Rated to 320 hp, the Larson Cabrio 310 2011 has a 70-hp advantage over the Larson FX 2050 DC O/B 2013's 250-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 2011 carries 160 gallons versus 35 gallons in the Larson FX 2050 DC O/B 2013. 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 310 2011 is rated for 9 passengers, while the Larson FX 2050 DC O/B 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Cabrio 310 2011 could be the deciding factor.
