Zodiac Cadet 310 S 2008 vs Zodiac Cadet RIB 310 2012 — Same Brand, Different Boat

Matching a inflatable non rigid Zodiac Cadet 310 S 2008 against a inflatable rigid Zodiac Cadet RIB 310 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.

Size is the most obvious dividing line here. The Zodiac Cadet RIB 310 2012 measures 10,2 feet overall (2012), giving it roughly 9,2 additional feet of deck space compared to the Zodiac Cadet 310 S 2008 at 1,0 feet (2008). At 93 lbs and 191 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 — 15 hp for the Zodiac Cadet 310 S 2008 and 20 hp for the Zodiac Cadet RIB 310 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.

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 Cadet 310 S 2008 comes in at 6 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 Cadet 310 S 2008 has a documented top speed of 22 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 Cadet 310 S 2008 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 at 10,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Cadet 310 S 2008 at 1,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Zodiac Cadet 310 S 2008 vs Zodiac Cadet RIB 310 2012 — Common Questions

Which is the larger boat — the Zodiac Cadet 310 S 2008 or the Zodiac Cadet RIB 310 2012?
The Zodiac Cadet RIB 310 2012 is the longer of the two at 10,2 feet overall. The Zodiac Cadet 310 S 2008 comes in at 1,0 feet, making it roughly 9,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Zodiac Cadet 310 S 2008 or the Zodiac Cadet RIB 310 2012?
For trailering, the Zodiac Cadet 310 S 2008 has the edge at 93 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 310 S 2008 is Coast Guard rated for 5 passengers, while the Zodiac Cadet RIB 310 2012 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 Cadet 310 S 2008 has a better power-to-weight ratio at 6 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.
Are the Zodiac Cadet 310 S 2008 and Zodiac Cadet RIB 310 2012 from the same manufacturer?
Yes — both the Zodiac Cadet 310 S 2008 and the Zodiac Cadet RIB 310 2012 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.
