Matching a inflatable rigid Zodiac Cadet RIB 310 2013 against a deep vee Zodiac N-ZO 690 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 N-ZO 690 2012 measures 22,9 feet overall (2012), giving it roughly 12,8 additional feet of deck space compared to the Zodiac Cadet RIB 310 2013 at 10,2 feet (2013). Weight tells a clearer story for trailering families: the Zodiac N-ZO 690 2012 tips the scales at 333 lbs — 141 lbs less than the Zodiac Cadet RIB 310 2013 at 192 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 250 hp, the Zodiac N-ZO 690 2012 has a 230-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.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac N-ZO 690 2012 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.
The Zodiac N-ZO 690 2012 has a documented top speed of 52 mph. Speed data wasn't available for the other model.
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. 2 in. (0.65 m) on the Zodiac N-ZO 690 2012 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: The Zodiac N-ZO 690 2012 at 22,9 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Cadet RIB 310 2013 at 10,2 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
