Matching a inflatable rigid Zodiac Cadet Compact 300 NEO 2013 against a deep vee Zodiac Medline 580 2013 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 580 2013 measures 19,0 feet overall (2013), giving it roughly 9,2 additional feet of deck space compared to the Zodiac Cadet Compact 300 NEO 2013 at 9,8 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Medline 580 2013 tips the scales at 1 325 lbs — 1 314 lbs less than the Zodiac Cadet Compact 300 NEO 2013 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 80 hp, the Zodiac Medline 580 2013 has a 70-hp advantage over the Zodiac Cadet Compact 300 NEO 2013's 10-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 580 2013 is rated for 12 passengers, while the Zodiac Cadet Compact 300 NEO 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 580 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet Compact 300 NEO 2013 comes in at 1 lbs per hp versus 17 lbs per hp for the Zodiac Medline 580 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.
The Zodiac Cadet Compact 300 NEO 2013 has a documented top speed of 21 mph. Speed data wasn't available for the other model.
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. 5 in. (0.42 m) on the Zodiac Cadet Compact 300 NEO 2013 vs 1 ft. 10 in. (0.55 m) on the Zodiac Medline 580 2013 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Zodiac Medline 580 2013 if your priority is putting more people on the water — it handles 12 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Compact 300 NEO 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.
