Matching a inflatable non rigid Zodiac Mark II ST 2009 against a inflatable rigid Zodiac Zoom 400 SR 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.

Both boats share a closely matched power ceiling — 40 hp for the Zodiac Mark II ST 2009 and 30 hp for the Zodiac Zoom 400 SR 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.
