Matching a modified vee Zodiac Bayrunner 420 2013 against a inflatable non rigid Zodiac Classic Mark 2 ST 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.
On paper these two are close siblings in the size department — Zodiac Bayrunner 420 2013 at 13,8 ft versus Zodiac Classic Mark 2 ST 2008 at 13,0 ft. Weight tells a clearer story for trailering families: the Zodiac Bayrunner 420 2013 tips the scales at 399 lbs — 217 lbs more than the Zodiac Classic Mark 2 ST 2008 at 182 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.
Both boats share a closely matched power ceiling — 50 hp for the Zodiac Bayrunner 420 2013 and 40 hp for the Zodiac Classic Mark 2 ST 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
Both boats are rated for 7 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 2 ST 2008 comes in at 5 lbs per hp versus 8 lbs per hp for the Zodiac Bayrunner 420 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 37 mph for the Zodiac Bayrunner 420 2013 and 33 mph for the Zodiac Classic Mark 2 ST 2008.
The Zodiac Bayrunner 420 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 2 ST 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 Bayrunner 420 2013 and Zodiac Classic Mark 2 ST 2008 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
