Matching a inflatable rigid Zodiac 350 S 2009 against a inflatable non rigid Zodiac Cadet Solid 310 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.

Both boats share a closely matched power ceiling — 20 hp for the Zodiac 350 S 2009 and 15 hp for the Zodiac Cadet Solid 310 2011. 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 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.

The Zodiac Cadet Solid 310 2011 has a documented top speed of 22 mph. Speed data wasn't available for the other model.
