When two boats share the same hull type — in this case both the Larson LXi 288 I/O 2011 and the Larson SEi 180 LX I/O 2006 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 288 I/O 2011 measures 29,2 feet overall (2011), giving it roughly 12,2 additional feet of deck space compared to the Larson SEi 180 LX I/O 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Larson SEi 180 LX I/O 2006 tips the scales at 2 365 lbs — 1 768 lbs less than the Larson LXi 288 I/O 2011 at 597 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 288 I/O 2011 carries a rated maximum of 430 hp. Engine data for the Larson SEi 180 LX I/O 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson SEi 180 LX I/O 2006 carries 23 gallons versus 1 gallons in the Larson LXi 288 I/O 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
