When two boats share the same hull type — in this case both the Larson FX 1750 DC O/B 2012 and the Larson LXi 238 2009 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 2009 measures 23,0 feet overall (2009), giving it roughly 5,6 additional feet of deck space compared to the Larson FX 1750 DC O/B 2012 at 17,4 feet (2012). Weight tells a clearer story for trailering families: the Larson LXi 238 2009 tips the scales at 444 lbs — 427 lbs less than the Larson FX 1750 DC O/B 2012 at 17 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 FX 1750 DC O/B 2012 carries a rated maximum of 150 hp. Engine data for the Larson LXi 238 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson LXi 238 2009 carries 56 gallons versus 23 gallons in the Larson FX 1750 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 1750 DC O/B 2012 is rated for 6 passengers, while the Larson LXi 238 2009 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 1750 DC O/B 2012 could be the deciding factor.
