Matching a inflatable non rigid Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 against a inflatable rigid Zodiac Zoom 400 SR 2008 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 Zoom 400 SR 2008 measures 13,0 feet overall (2008), giving it roughly 12,0 additional feet of deck space compared to the Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 at 1,0 feet (2008). Weight tells a clearer story for trailering families: the Zodiac Zoom 400 SR 2008 tips the scales at 254 lbs — 183 lbs less than the Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 at 71 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 — 10 hp for the Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 and 30 hp for the Zodiac Zoom 400 SR 2008. 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 Zoom 400 SR 2008 is rated for 7 passengers, while the Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom 400 SR 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 comes in at 7 lbs per hp versus 9 lbs per hp for the Zodiac Zoom 400 SR 2008. 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 Fastroller 310 FR Acti-V INT-L 2008 has a documented top speed of 23 mph. Speed data wasn't available for the other model.
Bottom line: Choose the Zodiac Zoom 400 SR 2008 if your priority is putting more people on the water — it handles 7 passengers and at 13,0 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Fastroller 310 FR Acti-V INT-L 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
