When two boats share the same hull type — in this case both the Mercury 350 Amanzi 2009 and the Mercury 350 Ocean Runner PVC 2013 are inflatable rigid designs with rigid inflatable 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 — Mercury 350 Amanzi 2009 at 11,0 ft versus Mercury 350 Ocean Runner PVC 2013 at 11,2 ft. Weight tells a clearer story for trailering families: the Mercury 350 Ocean Runner PVC 2013 tips the scales at 184 lbs — 180 lbs less than the Mercury 350 Amanzi 2009 at 4 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.

Both boats share a closely matched power ceiling — 30 hp for the Mercury 350 Amanzi 2009 and 25 hp for the Mercury 350 Ocean Runner PVC 2013. 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 Mercury 350 Ocean Runner PVC 2013 is rated for 5 passengers, while the Mercury 350 Amanzi 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury 350 Ocean Runner PVC 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 350 Amanzi 2009 comes in at 0 lbs per hp versus 7 lbs per hp for the Mercury 350 Ocean Runner PVC 2013. 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.
