Matching a inflatable rigid Zodiac Cadet RIB 310 2012 against a inflatable non rigid Zodiac Classic Mark I Solid 2013 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 — Zodiac Cadet RIB 310 2012 at 10,2 ft versus Zodiac Classic Mark I Solid 2013 at 11,5 ft. At 191 lbs and 134 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 — 20 hp for the Zodiac Cadet RIB 310 2012 and 25 hp for the Zodiac Classic Mark I Solid 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.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Classic Mark I Solid 2013 comes in at 5 lbs per hp versus 10 lbs per hp for the Zodiac Cadet RIB 310 2012. 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.
The Zodiac Classic Mark I Solid 2013 has a documented top speed of 28 mph. Speed data wasn't available for the other model.
The Zodiac Cadet RIB 310 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Classic Mark I Solid 2013 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Zodiac Cadet RIB 310 2012 and Zodiac Classic Mark I Solid 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
