Matching a inflatable non rigid Zodiac Cadet 285 Solid 2013 against a deep vee Zodiac Medline IV 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 Medline IV 2012 measures 27,9 feet overall (2012), giving it roughly 18,6 additional feet of deck space compared to the Zodiac Cadet 285 Solid 2013 at 9,3 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Medline IV 2012 tips the scales at 3 527 lbs — 3 441 lbs less than the Zodiac Cadet 285 Solid 2013 at 86 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 350 hp, the Zodiac Medline IV 2012 has a 342-hp advantage over the Zodiac Cadet 285 Solid 2013'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 Medline IV 2012 is rated for 8 passengers, while the Zodiac Cadet 285 Solid 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Medline IV 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Medline IV 2012 comes in at 10 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 57 mph for the Zodiac Medline IV 2012 and 17 mph for the Zodiac Cadet 285 Solid 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. 6 in. (0.45 m) on the Zodiac Cadet 285 Solid 2013 vs 2 ft. (0.6 m) on the Zodiac Medline IV 2012 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Zodiac Medline IV 2012 if your priority is putting more people on the water — it handles 8 passengers and at 27,9 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet 285 Solid 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
