Matching a inflatable rigid Zodiac Medline II 2008 against a inflatable non rigid Zodiac Zoom 350 S 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 II 2008 measures 19,0 feet overall (2008), giving it roughly 7,5 additional feet of deck space compared to the Zodiac Zoom 350 S 2012 at 11,5 feet (2012). Weight tells a clearer story for trailering families: the Zodiac Medline II 2008 tips the scales at 1 432 lbs — 1 289 lbs more than the Zodiac Zoom 350 S 2012 at 143 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 130-hp advantage over the Zodiac Zoom 350 S 2012's 20-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Zoom 350 S 2012 comes in at 7 lbs per hp versus 10 lbs per hp for the Zodiac Medline II 2008. 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 Medline II 2008 has a documented top speed of 46 mph. Speed data wasn't available for the other model.
The Zodiac Zoom 350 S 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Medline II 2008 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Zodiac Medline II 2008 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Zoom 350 S 2012 at 11,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
