Matching a inflatable rigid Zodiac Cadet RIB 310 2013 against a deep vee Zodiac N-ZO 600 2013 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 N-ZO 600 2013 measures 19,7 feet overall (2013), giving it roughly 9,5 additional feet of deck space compared to the Zodiac Cadet RIB 310 2013 at 10,2 feet (2013). At 192 lbs and 205 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.
The power gap is worth calling out. Rated to 150 hp, the Zodiac N-ZO 600 2013 has a 130-hp advantage over the Zodiac Cadet RIB 310 2013's 20-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 N-ZO 600 2013 is rated for 12 passengers, while the Zodiac Cadet RIB 310 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac N-ZO 600 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac N-ZO 600 2013 comes in at 1 lbs per hp versus 10 lbs per hp for the Zodiac Cadet RIB 310 2013. 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.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly. Tube diameter differs: 1 ft. 6 in. (0.45 m) on the Zodiac Cadet RIB 310 2013 vs 2 ft. (0.6 m) on the Zodiac N-ZO 600 2013 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Zodiac N-ZO 600 2013 if your priority is putting more people on the water — it handles 12 passengers and at 19,7 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet RIB 310 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
