Matching a modified vee Zodiac Bayrunner 650 2013 against a inflatable non rigid Zodiac Classic Mark 1 ST 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 Bayrunner 650 2013 measures 21,3 feet overall (2013), giving it roughly 9,8 additional feet of deck space compared to the Zodiac Classic Mark 1 ST 2011 at 11,5 feet (2011). Weight tells a clearer story for trailering families: the Zodiac Bayrunner 650 2013 tips the scales at 1 257 lbs — 1 122 lbs more than the Zodiac Classic Mark 1 ST 2011 at 135 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 90 hp, the Zodiac Bayrunner 650 2013 has a 65-hp advantage over the Zodiac Classic Mark 1 ST 2011's 25-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 Classic Mark 1 ST 2011 comes in at 5 lbs per hp versus 14 lbs per hp for the Zodiac Bayrunner 650 2013. 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 Bayrunner 650 2013 and 28 mph for the Zodiac Classic Mark 1 ST 2011.
The Zodiac Bayrunner 650 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Classic Mark 1 ST 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Zodiac Bayrunner 650 2013 at 21,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Classic Mark 1 ST 2011 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.
