Matching a modified vee Zodiac Bayrunner 340 2013 against a inflatable rigid Zodiac Pro Open 650 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 Pro Open 650 2008 measures 21,0 feet overall (2008), giving it roughly 9,8 additional feet of deck space compared to the Zodiac Bayrunner 340 2013 at 11,2 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Pro Open 650 2008 tips the scales at 1 388 lbs — 1 174 lbs less than the Zodiac Bayrunner 340 2013 at 214 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 2008 has a 150-hp advantage over the Zodiac Bayrunner 340 2013'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 Bayrunner 340 2013 is rated for 6 passengers, while the Zodiac Pro Open 650 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Bayrunner 340 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Pro Open 650 2008 comes in at 8 lbs per hp versus 9 lbs per hp for the Zodiac Bayrunner 340 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.
The Zodiac Pro Open 650 2008 has a documented top speed of 48 mph. Speed data wasn't available for the other model.
The Zodiac Bayrunner 340 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Pro Open 650 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 Bayrunner 340 2013 if your priority is putting more people on the water — it handles 6 passengers and at 11,2 ft it has the deck room to back that rating up comfortably. The Zodiac Pro Open 650 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
