When two boats share the same hull type — in this case both the Zodiac Cadet RIB 340 2011 and the Zodiac Commando C4 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 340 2011 at 11,2 ft versus Zodiac Commando C4 2012 at 14,1 ft. Weight tells a clearer story for trailering families: the Zodiac Cadet RIB 340 2011 tips the scales at 172 lbs — 148 lbs more than the Zodiac Commando C4 2012 at 24 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 50 hp, the Zodiac Commando C4 2012 has a 25-hp advantage over the Zodiac Cadet RIB 340 2011's 25-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 Commando C4 2012 is rated for 7 passengers, while the Zodiac Cadet RIB 340 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Commando C4 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Commando C4 2012 comes in at 1 lbs per hp versus 7 lbs per hp for the Zodiac Cadet RIB 340 2011. 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 37 mph for the Zodiac Commando C4 2012 and 30 mph for the Zodiac Cadet RIB 340 2011.
The Zodiac Commando C4 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 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 Commando C4 2012 if your priority is putting more people on the water — it handles 7 passengers and at 14,1 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet RIB 340 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
