When two boats share the same hull type — in this case both the Zodiac 325 ACTI-V INT-L 2009 and the Zodiac Cadet Fastroller 285 FR Acti-V 2008 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 — 10 hp for the Zodiac 325 ACTI-V INT-L 2009 and 8 hp for the Zodiac Cadet Fastroller 285 FR Acti-V 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.
For family outings this is probably the sharpest distinction between the two. The Zodiac 325 ACTI-V INT-L 2009 is rated for 5 passengers, while the Zodiac Cadet Fastroller 285 FR Acti-V 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac 325 ACTI-V INT-L 2009 could be the deciding factor.
The Zodiac Cadet Fastroller 285 FR Acti-V 2008 has a documented top speed of 20 mph. Speed data wasn't available for the other model.
Bottom line: Choose the Zodiac 325 ACTI-V INT-L 2009 if your priority is putting more people on the water — it handles 5 passengers and at 10,7 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Fastroller 285 FR Acti-V 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
