When two boats share the same hull type — in this case both the Zodiac Cadet RIB 220 2010 and the Zodiac Medline II 2008 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?

Size is the most obvious dividing line here. The Zodiac Medline II 2008 measures 19,0 feet overall (2008), giving it roughly 11,8 additional feet of deck space compared to the Zodiac Cadet RIB 220 2010 at 7,3 feet (2010). Weight tells a clearer story for trailering families: the Zodiac Medline II 2008 tips the scales at 1 432 lbs — 1 364 lbs less than the Zodiac Cadet RIB 220 2010 at 68 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 150 hp, the Zodiac Medline II 2008 has a 146-hp advantage over the Zodiac Cadet RIB 220 2010's 4-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 II 2008 is rated for 5 passengers, while the Zodiac Cadet RIB 220 2010 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Medline II 2008 could be the deciding factor.
