Matching a inflatable non rigid Zodiac Classic Mark II C Solid 2013 against a inflatable rigid Zodiac Pro Open 650 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 Pro Open 650 2012 measures 21,3 feet overall (2012), giving it roughly 8,8 additional feet of deck space compared to the Zodiac Classic Mark II C Solid 2013 at 12,5 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Pro Open 650 2012 tips the scales at 1 477 lbs — 1 314 lbs less than the Zodiac Classic Mark II C Solid 2013 at 163 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 175 hp, the Zodiac Pro Open 650 2012 has a 140-hp advantage over the Zodiac Classic Mark II C Solid 2013's 35-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 Classic Mark II C Solid 2013 is rated for 6 passengers, while the Zodiac Pro Open 650 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 Classic Mark II C Solid 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Classic Mark II C Solid 2013 comes in at 5 lbs per hp versus 8 lbs per hp for the Zodiac Pro Open 650 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.
Top speed is rated at 48 mph for the Zodiac Pro Open 650 2012 and 31 mph for the Zodiac Classic Mark II C Solid 2013.
The Zodiac Pro Open 650 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Classic Mark II C Solid 2013 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 Classic Mark II C Solid 2013 if your priority is putting more people on the water — it handles 6 passengers and at 12,5 ft it has the deck room to back that rating up comfortably. The Zodiac Pro Open 650 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.
