When two boats share the same hull type — in this case both the Larson LX 950 I/O 2012 and the Larson Senza 186 2009 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 950 I/O 2012 at 19,4 ft versus Larson Senza 186 2009 at 18,0 ft. At 27 lbs and 27 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 Larson LX 950 I/O 2012 carries a rated maximum of 22 hp. Engine data for the Larson Senza 186 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson Senza 186 2009 carries 29 gallons versus 3 gallons in the Larson LX 950 I/O 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 Senza 186 2009 is rated for 9 passengers, while the Larson LX 950 I/O 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Senza 186 2009 could be the deciding factor.
