Matching a modified vee Zodiac Bayrunner 550 2013 against a deep vee Zodiac N-ZO 690 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 N-ZO 690 2011 measures 22,9 feet overall (2011), giving it roughly 4,8 additional feet of deck space compared to the Zodiac Bayrunner 550 2013 at 18,1 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Bayrunner 550 2013 tips the scales at 694 lbs — 361 lbs more than the Zodiac N-ZO 690 2011 at 333 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 N-ZO 690 2011 has a 210-hp advantage over the Zodiac Bayrunner 550 2013's 40-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 550 2013 is rated for 12 passengers, while the Zodiac N-ZO 690 2011 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 550 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac N-ZO 690 2011 comes in at 1 lbs per hp versus 17 lbs per hp for the Zodiac Bayrunner 550 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 52 mph for the Zodiac N-ZO 690 2011 and 42 mph for the Zodiac Bayrunner 550 2013.
The Zodiac Bayrunner 550 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac N-ZO 690 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 Bayrunner 550 2013 if your priority is putting more people on the water — it handles 12 passengers and at 18,1 ft it has the deck room to back that rating up comfortably. The Zodiac N-ZO 690 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
