When two boats share the same hull type — in this case both the Zodiac Cadet 310 S 2008 and the Zodiac MAX 2 Aero 2012 are inflatable non rigid designs with inflatable 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?
Size is the most obvious dividing line here. The Zodiac MAX 2 Aero 2012 measures 7,9 feet overall (2012), giving it roughly 6,9 additional feet of deck space compared to the Zodiac Cadet 310 S 2008 at 1,0 feet (2008). At 93 lbs and 57 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.
Both boats share a closely matched power ceiling — 15 hp for the Zodiac Cadet 310 S 2008 and 4 hp for the Zodiac MAX 2 Aero 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Zodiac Cadet 310 S 2008 is rated for 5 passengers, while the Zodiac MAX 2 Aero 2012 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Cadet 310 S 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet 310 S 2008 comes in at 6 lbs per hp versus 14 lbs per hp for the Zodiac MAX 2 Aero 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 22 mph for the Zodiac Cadet 310 S 2008 and 5 mph for the Zodiac MAX 2 Aero 2012.
The Zodiac MAX 2 Aero 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Cadet 310 S 2008 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 310 S 2008 if your priority is putting more people on the water — it handles 5 passengers and at 1,0 ft it has the deck room to back that rating up comfortably. The Zodiac MAX 2 Aero 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
