When two boats share the same hull type — in this case both the Larson FX 1850 DC O/B 2012 and the Larson LXi 238 I/O 2011 are modified 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 LXi 238 I/O 2011 measures 23,5 feet overall (2011), giving it roughly 5,0 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 LXi 238 I/O 2011 tips the scales at 444 lbs — 262 lbs less than the Larson FX 1850 DC O/B 2012 at 182 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 LXi 238 I/O 2011 has a 145-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 LXi 238 I/O 2011 carries 54 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.

For family outings this is probably the sharpest distinction between the two. The Larson FX 1850 DC O/B 2012 is rated for 7 passengers, while the Larson LXi 238 I/O 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson FX 1850 DC O/B 2012 could be the deciding factor.
