When two boats share the same hull type — in this case both the Larson LXi 288 2009 and the Larson Senza 186 O/B 2007 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 2009 measures 29,0 feet overall (2009), giving it roughly 11,0 additional feet of deck space compared to the Larson Senza 186 O/B 2007 at 18,0 feet (2007). Weight tells a clearer story for trailering families: the Larson LXi 288 2009 tips the scales at 6 225 lbs — 4 440 lbs more than the Larson Senza 186 O/B 2007 at 1 785 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 Senza 186 O/B 2007 tops out at 175 hp. Engine specs for the Larson LXi 288 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Larson Senza 186 O/B 2007 carries 29 gallons versus 1 gallons in the Larson LXi 288 2009. 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.
Bottom line: The Larson LXi 288 2009 at 29,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Larson Senza 186 O/B 2007 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
