Matching a deep vee Zodiac Medline IV 2012 against a inflatable non rigid Zodiac Zoom 380 S 2008 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 15,9 additional feet of deck space compared to the Zodiac Zoom 380 S 2008 at 12,0 feet (2008). Weight tells a clearer story for trailering families: the Zodiac Medline IV 2012 tips the scales at 3 527 lbs — 3 406 lbs more than the Zodiac Zoom 380 S 2008 at 121 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 335-hp advantage over the Zodiac Zoom 380 S 2008's 15-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 Zoom 380 S 2008 caps at 6. 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 Zoom 380 S 2008 comes in at 8 lbs per hp versus 10 lbs per hp for the Zodiac Medline IV 2012. 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 IV 2012 has a documented top speed of 57 mph. Speed data wasn't available for the other model.
The Zodiac Medline IV 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Zoom 380 S 2008 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
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 Zoom 380 S 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
