When two boats share the same hull type — in this case both the Larson LXi 238 I/O 2011 and the Larson SEi 180 LX 2009 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 LXi 238 I/O 2011 measures 23,5 feet overall (2011), giving it roughly 6,5 additional feet of deck space compared to the Larson SEi 180 LX 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Larson SEi 180 LX 2009 tips the scales at 2 365 lbs — 1 921 lbs less than the Larson LXi 238 I/O 2011 at 444 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 LXi 238 I/O 2011 carries a rated maximum of 320 hp. Engine data for the Larson SEi 180 LX 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 I/O 2011 carries 54 gallons versus 23 gallons in the Larson SEi 180 LX 2009. 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 SEi 180 LX 2009 is rated for 8 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 SEi 180 LX 2009 could be the deciding factor.
Bottom line: Choose the Larson SEi 180 LX 2009 if your priority is putting more people on the water — it handles 8 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Larson LXi 238 I/O 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
