Matching a inflatable non rigid Zodiac Classic Mark 1 HD 2012 against a deep vee Zodiac Medline III 2011 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 III 2011 measures 24,0 feet overall (2011), giving it roughly 12,5 additional feet of deck space compared to the Zodiac Classic Mark 1 HD 2012 at 11,5 feet (2012). Weight tells a clearer story for trailering families: the Zodiac Medline III 2011 tips the scales at 3 087 lbs — 2 946 lbs less than the Zodiac Classic Mark 1 HD 2012 at 141 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 250 hp, the Zodiac Medline III 2011 has a 225-hp advantage over the Zodiac Classic Mark 1 HD 2012's 25-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 III 2011 is rated for 8 passengers, while the Zodiac Classic Mark 1 HD 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Medline III 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Classic Mark 1 HD 2012 comes in at 6 lbs per hp versus 12 lbs per hp for the Zodiac Medline III 2011. 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 53 mph for the Zodiac Medline III 2011 and 28 mph for the Zodiac Classic Mark 1 HD 2012.
The Zodiac Classic Mark 1 HD 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Medline III 2011 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 III 2011 if your priority is putting more people on the water — it handles 8 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Zodiac Classic Mark 1 HD 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
