When two boats share the same hull type — in this case both the Livingston Model 16 2010 and the Livingston Model 19 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?
On paper these two are close siblings in the size department — Livingston Model 16 2010 at 15,5 ft versus Livingston Model 19 2010 at 18,5 ft. At 1 lbs and 15 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 — 105 hp for the Livingston Model 16 2010 and 90 hp for the Livingston Model 19 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 19 2010 is rated for 8 passengers, while the Livingston Model 16 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Livingston Model 19 2010 could be the deciding factor.
Bottom line: Choose the Livingston Model 19 2010 if your priority is putting more people on the water — it handles 8 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The Livingston Model 16 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
