Matching a inflatable non rigid Zodiac Cadet Fastroller 360 ACTI-V INT-L 2011 against a inflatable rigid Zodiac Cadet RIB 310 2011 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 Fastroller 360 ACTI-V INT-L 2011 at 11,8 ft versus Zodiac Cadet RIB 310 2011 at 10,2 ft. At 97 lbs and 143 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 Fastroller 360 ACTI-V INT-L 2011 and 15 hp for the Zodiac Cadet RIB 310 2011. 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 Cadet Fastroller 360 ACTI-V INT-L 2011 is rated for 6 passengers, while the Zodiac Cadet RIB 310 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Cadet Fastroller 360 ACTI-V INT-L 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet Fastroller 360 ACTI-V INT-L 2011 comes in at 7 lbs per hp versus 10 lbs per hp for the Zodiac Cadet RIB 310 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.
Top speed is rated at 26 mph for the Zodiac Cadet Fastroller 360 ACTI-V INT-L 2011 and 24 mph for the Zodiac Cadet RIB 310 2011.
Bottom line: Choose the Zodiac Cadet Fastroller 360 ACTI-V INT-L 2011 if your priority is putting more people on the water — it handles 6 passengers and at 11,8 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet RIB 310 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
