When two boats share the same hull type — in this case both the Larson LX 620 O/B 2011 and the Larson LX 860 O/B 2012 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?

On paper these two are close siblings in the size department — Larson LX 620 O/B 2011 at 16,2 ft versus Larson LX 860 O/B 2012 at 18,5 ft. At 115 lbs and 178 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 150 hp, the Larson LX 860 O/B 2012 has a 60-hp advantage over the Larson LX 620 O/B 2011's 90-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 LX 620 O/B 2011 carries 23 gallons versus 3 gallons in the Larson LX 860 O/B 2012. 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 LX 860 O/B 2012 is rated for 8 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 LX 860 O/B 2012 could be the deciding factor.
