When two boats share the same hull type — in this case both the Zodiac 325 ACTI-V INT-L 2009 and the Zodiac Classic Mark 2 ST 2012 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?
The power gap is worth calling out. Rated to 40 hp, the Zodiac Classic Mark 2 ST 2012 has a 30-hp advantage over the Zodiac 325 ACTI-V INT-L 2009's 10-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 Classic Mark 2 ST 2012 is rated for 7 passengers, while the Zodiac 325 ACTI-V INT-L 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Classic Mark 2 ST 2012 could be the deciding factor.
The Zodiac Classic Mark 2 ST 2012 has a documented top speed of 34 mph. Speed data wasn't available for the other model.
The Zodiac Classic Mark 2 ST 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac 325 ACTI-V INT-L 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 Classic Mark 2 ST 2012 if your priority is putting more people on the water — it handles 7 passengers and at 13,8 ft it has the deck room to back that rating up comfortably. The Zodiac 325 ACTI-V INT-L 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
