Matching a inflatable rigid Zodiac Cadet RIB 310 2010 against a inflatable non rigid Zodiac Typhoon 420 S 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 Typhoon 420 S 2012 measures 13,8 feet overall (2012), giving it roughly 3,6 additional feet of deck space compared to the Zodiac Cadet RIB 310 2010 at 10,2 feet (2010). Weight tells a clearer story for trailering families: the Zodiac Cadet RIB 310 2010 tips the scales at 143 lbs — 125 lbs more than the Zodiac Typhoon 420 S 2012 at 18 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 — 15 hp for the Zodiac Cadet RIB 310 2010 and 19 hp for the Zodiac Typhoon 420 S 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 Zodiac Typhoon 420 S 2012 is rated for 7 passengers, while the Zodiac Cadet RIB 310 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Typhoon 420 S 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Typhoon 420 S 2012 comes in at 1 lbs per hp versus 10 lbs per hp for the Zodiac Cadet RIB 310 2010. 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.
Top speed is rated at 25 mph for the Zodiac Typhoon 420 S 2012 and 24 mph for the Zodiac Cadet RIB 310 2010.
The Zodiac Typhoon 420 S 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Cadet RIB 310 2010 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Zodiac Typhoon 420 S 2012 if your priority is putting more people on the water — it handles 7 passengers and at 13,8 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet RIB 310 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
