When two boats share the same hull type — in this case both the Livingston Model 10 2011 and the Livingston Model 12 2010 are catamaran 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 Livingston Model 12 2010 measures 11,9 feet overall (2010), giving it roughly 10,9 additional feet of deck space compared to the Livingston Model 10 2011 at 1,0 feet (2011). At 19 lbs and 16 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.

Both boats share a closely matched power ceiling — 10 hp for the Livingston Model 10 2011 and 15 hp for the Livingston Model 12 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The Livingston Model 12 2010 is rated for 5 passengers, while the Livingston Model 10 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Livingston Model 12 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Livingston Model 12 2010 comes in at 1 lbs per hp versus 2 lbs per hp for the Livingston Model 10 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
