When two boats share the same hull type — in this case both the Larson LX 620 O/B 2011 and the Larson LXi 208 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 LX 620 O/B 2011 measures 16,2 feet overall (2011), giving it roughly 14,2 additional feet of deck space compared to the Larson LXi 208 I/O 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Larson LXi 208 I/O 2006 tips the scales at 3 245 lbs — 3 130 lbs less than the Larson LX 620 O/B 2011 at 115 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 LX 620 O/B 2011 carries a rated maximum of 90 hp. Engine data for the Larson LXi 208 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 LXi 208 I/O 2006 carries 29 gallons versus 23 gallons in the Larson LX 620 O/B 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 208 I/O 2006 is rated for 9 passengers, while the Larson LX 620 O/B 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 208 I/O 2006 could be the deciding factor.
Bottom line: Choose the Larson LXi 208 I/O 2006 if your priority is putting more people on the water — it handles 9 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Larson LX 620 O/B 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
