Matching a inflatable non rigid Zodiac AX 3 2012 against a inflatable rigid Zodiac Cadet RIB 340 2010 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 AX 3 2012 at 8,5 ft versus Zodiac Cadet RIB 340 2010 at 11,2 ft. Weight tells a clearer story for trailering families: the Zodiac Cadet RIB 340 2010 tips the scales at 172 lbs — 108 lbs less than the Zodiac AX 3 2012 at 64 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.
The power gap is worth calling out. Rated to 25 hp, the Zodiac Cadet RIB 340 2010 has a 21-hp advantage over the Zodiac AX 3 2012's 4-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Zodiac Cadet RIB 340 2010 is rated for 5 passengers, while the Zodiac AX 3 2012 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Cadet RIB 340 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet RIB 340 2010 comes in at 7 lbs per hp versus 16 lbs per hp for the Zodiac AX 3 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.
Top speed is rated at 30 mph for the Zodiac Cadet RIB 340 2010 and 6 mph for the Zodiac AX 3 2012.
The Zodiac AX 3 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 340 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 Cadet RIB 340 2010 if your priority is putting more people on the water — it handles 5 passengers and at 11,2 ft it has the deck room to back that rating up comfortably. The Zodiac AX 3 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
