Matching a inflatable rigid Mercury 310 Dynamic RIB Hypalon 2011 against a inflatable non rigid Mercury 340 Sport PVC 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Mercury 310 Dynamic RIB Hypalon 2011 at 10,2 ft versus Mercury 340 Sport PVC 2012 at 10,5 ft. At 114 lbs and 124 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 Mercury 310 Dynamic RIB Hypalon 2011 and 20 hp for the Mercury 340 Sport PVC 2012. 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 340 Sport PVC 2012 is rated for 5 passengers, while the Mercury 310 Dynamic RIB Hypalon 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury 340 Sport PVC 2012 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 340 Sport PVC 2012 comes in at 6 lbs per hp versus 12 lbs per hp for the Mercury 310 Dynamic RIB Hypalon 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.
