When two boats share the same hull type — in this case both the Larson 274 Cabrio 2010 and the Larson FX 1850 DC O/B 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 274 Cabrio 2010 measures 28,0 feet overall (2010), giving it roughly 9,5 additional feet of deck space compared to the Larson FX 1850 DC O/B 2012 at 18,5 feet (2012). Weight tells a clearer story for trailering families: the Larson FX 1850 DC O/B 2012 tips the scales at 182 lbs — 176 lbs less than the Larson 274 Cabrio 2010 at 6 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 375 hp, the Larson 274 Cabrio 2010 has a 200-hp advantage over the Larson FX 1850 DC O/B 2012's 175-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 274 Cabrio 2010 carries 85 gallons versus 35 gallons in the Larson FX 1850 DC O/B 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
