Zodiac Cadet RIB 310 2012 vs Zodiac Classic Mark I Solid 2013 — Same Brand, Different Boat

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.

Zodiac Cadet RIB 310 2012 vs Zodiac Classic Mark I Solid 2013 — Common Questions

Which is the larger boat — the Zodiac Cadet RIB 310 2012 or the Zodiac Classic Mark I Solid 2013?
The Zodiac Classic Mark I Solid 2013 is the longer of the two at 11,5 feet overall. The Zodiac Cadet RIB 310 2012 comes in at 10,2 feet, making it roughly 1,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Zodiac Cadet RIB 310 2012 or the Zodiac Classic Mark I Solid 2013?
For trailering, the Zodiac Classic Mark I Solid 2013 has the edge at 134 lbs dry weight versus 191 lbs for the Zodiac Cadet RIB 310 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Zodiac Cadet RIB 310 2012 is Coast Guard rated for 5 passengers, while the Zodiac Classic Mark I Solid 2013 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Zodiac Classic Mark I Solid 2013 has a better power-to-weight ratio at 5 lbs per hp compared to 10 lbs per hp for the Zodiac Cadet RIB 310 2012. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Zodiac Cadet RIB 310 2012 measures 68" wide, compared to 63" for the Zodiac Classic Mark I Solid 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Zodiac Cadet RIB 310 2012 and Zodiac Classic Mark I Solid 2013 from the same manufacturer?
Yes — both the Zodiac Cadet RIB 310 2012 and the Zodiac Classic Mark I Solid 2013 are built by Zodiac. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
