When two boats share the same hull type — in this case both the Zodiac 360 ACTI-V INT-L 2009 and the Zodiac Mark II C HD 2009 are inflatable non rigid designs with inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Both boats share a closely matched power ceiling — 15 hp for the Zodiac 360 ACTI-V INT-L 2009 and 35 hp for the Zodiac Mark II C HD 2009. 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 6 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.
Bottom line: Performance buyers should lean toward the Zodiac Mark II C HD 2009 and its 35-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Zodiac 360 ACTI-V INT-L 2009 with its 15-hp rating is the more economical daily driver.
