When two boats share the same hull type — in this case both the Zodiac Cadet 240 Aero 2013 and the Zodiac Cadet 285 Solid 2013 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?
On paper these two are close siblings in the size department — Zodiac Cadet 240 Aero 2013 at 7,8 ft versus Zodiac Cadet 285 Solid 2013 at 9,3 ft. At 6 lbs and 86 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 — 4 hp for the Zodiac Cadet 240 Aero 2013 and 8 hp for the Zodiac Cadet 285 Solid 2013. 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 285 Solid 2013 is rated for 4 passengers, while the Zodiac Cadet 240 Aero 2013 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 285 Solid 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet 240 Aero 2013 comes in at 2 lbs per hp versus 11 lbs per hp for the Zodiac Cadet 285 Solid 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.
Top speed is rated at 17 mph for the Zodiac Cadet 285 Solid 2013 and 12 mph for the Zodiac Cadet 240 Aero 2013.
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. 4 in. (0.4 m) on the Zodiac Cadet 240 Aero 2013 vs 1 ft. 6 in. (0.45 m) on the Zodiac Cadet 285 Solid 2013 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Zodiac Cadet 285 Solid 2013 if your priority is putting more people on the water — it handles 4 passengers and at 9,3 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet 240 Aero 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
