When two boats share the same hull type — in this case both the Larson 288 LXi 2010 and the Larson LXi 238 I/O 2011 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 288 LXi 2010 measures 29,2 feet overall (2010), giving it roughly 5,7 additional feet of deck space compared to the Larson LXi 238 I/O 2011 at 23,5 feet (2011). Weight tells a clearer story for trailering families: the Larson 288 LXi 2010 tips the scales at 597 lbs — 153 lbs more 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 power gap is worth calling out. Rated to 425 hp, the Larson 288 LXi 2010 has a 105-hp advantage over the Larson LXi 238 I/O 2011's 320-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 1 gallons in the Larson 288 LXi 2010. 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 288 LXi 2010 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 288 LXi 2010 could be the deciding factor.
