Both the Larson LX 850 I/O 2011 and the Larson LXi 288 I/O 2012 are modified-V designs, the first built in fibreglass and the second in composite, so 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 2012 measures 29,2 feet overall (2012), giving it roughly 10,8 additional feet of deck space compared to the Larson LX 850 I/O 2011 at 18,4 feet (2011). Weight tells a clearer story for trailering families: the Larson LXi 288 I/O 2012 tips the scales at 5 970 lbs - 3 520 lbs less than the Larson LX 850 I/O 2011 at 2 450 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 300 hp, the Larson LXi 288 I/O 2012 has a 75-hp advantage over the Larson LX 850 I/O 2011's 225-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 288 I/O 2012 carries 100 gallons versus 23 gallons in the Larson LX 850 I/O 2011. 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 LXi 288 I/O 2012 is rated for 8 passengers, while the Larson LX 850 I/O 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 288 I/O 2012 could be the deciding factor.
