When two boats share the same hull type — in this case both the Zodiac Cadet RIB 260 2011 and the Zodiac Cadet RIB 340 2012 are inflatable rigid designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Zodiac Cadet RIB 260 2011 at 8,5 ft versus Zodiac Cadet RIB 340 2012 at 11,2 ft. Weight tells a clearer story for trailering families: the Zodiac Cadet RIB 340 2012 tips the scales at 207 lbs — 196 lbs less than the Zodiac Cadet RIB 260 2011 at 11 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 30 hp, the Zodiac Cadet RIB 340 2012 has a 22-hp advantage over the Zodiac Cadet RIB 260 2011's 8-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 2012 is rated for 6 passengers, while the Zodiac Cadet RIB 260 2011 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 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet RIB 260 2011 comes in at 1 lbs per hp versus 7 lbs per hp for the Zodiac Cadet RIB 340 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.
The Zodiac Cadet RIB 260 2011 has a documented top speed of 19 mph. Speed data wasn't available for the other model.
The Zodiac Cadet RIB 340 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 260 2011 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 2012 if your priority is putting more people on the water — it handles 6 passengers and at 11,2 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet RIB 260 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
