Larson LX 860 SF O/B 2012 vs Larson LX 950 I/O 2012 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Larson LX 860 SF O/B 2012 and the Larson LX 950 I/O 2012 are modified vee designs with composite 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 860 SF O/B 2012 at 18,5 ft versus Larson LX 950 I/O 2012 at 19,4 ft. Weight tells a clearer story for trailering families: the Larson LX 860 SF O/B 2012 tips the scales at 178 lbs — 151 lbs more than the Larson LX 950 I/O 2012 at 27 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 150 hp, the Larson LX 860 SF O/B 2012 has a 128-hp advantage over the Larson LX 950 I/O 2012's 22-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

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: Performance buyers should lean toward the Larson LX 860 SF O/B 2012 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Larson LX 950 I/O 2012 with its 22-hp rating is the more economical daily driver.

Larson LX 860 SF O/B 2012 vs Larson LX 950 I/O 2012 — Common Questions

Which is the larger boat — the Larson LX 860 SF O/B 2012 or the Larson LX 950 I/O 2012?
The Larson LX 950 I/O 2012 is the longer of the two at 19,4 feet overall. The Larson LX 860 SF O/B 2012 comes in at 18,5 feet, making it roughly 0,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Larson LX 860 SF O/B 2012 or the Larson LX 950 I/O 2012?
For trailering, the Larson LX 950 I/O 2012 has the edge at 27 lbs dry weight versus 178 lbs for the Larson LX 860 SF O/B 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Larson LX 860 SF O/B 2012 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Larson LX 950 I/O 2012 tops out at 22 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Larson LX 860 SF O/B 2012 is Coast Guard rated for 8 passengers, while the Larson LX 950 I/O 2012 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Larson LX 950 I/O 2012 measures 96" wide, compared to 94" for the Larson LX 860 SF O/B 2012. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Larson LX 860 SF O/B 2012 and Larson LX 950 I/O 2012?
Both boats carry similar fuel loads — 3 gallons and 3 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Larson LX 860 SF O/B 2012 and Larson LX 950 I/O 2012 from the same manufacturer?
Yes — both the Larson LX 860 SF O/B 2012 and the Larson LX 950 I/O 2012 are built by Larson. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
