Matching a modified vee Zodiac Bayrunner 550 2013 against a inflatable non rigid Zodiac Cadet Roll Up 240 2009 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.
The power gap is worth calling out. Rated to 40 hp, the Zodiac Bayrunner 550 2013 has a 36-hp advantage over the Zodiac Cadet Roll Up 240 2009's 4-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 Cadet Roll Up 240 2009 caps at 3. 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.
The Zodiac Bayrunner 550 2013 has a documented top speed of 42 mph. Speed data wasn't available for the other model.
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 Cadet Roll Up 240 2009 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 Cadet Roll Up 240 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
