When two boats share the same hull type — in this case both the Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012 and the Zodiac Classic Mark 2C 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?
On paper these two are close siblings in the size department — Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012 at 10,7 ft versus Zodiac Classic Mark 2C ST 2012 at 12,5 ft. At 88 lbs and 163 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 35 hp, the Zodiac Classic Mark 2C ST 2012 has a 25-hp advantage over the Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012'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 2C ST 2012 is rated for 6 passengers, while the Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012 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 2C ST 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Classic Mark 2C ST 2012 comes in at 5 lbs per hp versus 9 lbs per hp for the Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Top speed is rated at 31 mph for the Zodiac Classic Mark 2C ST 2012 and 23 mph for the Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly. Tube diameter differs: 1 ft. 6 in. (0.45 m) on the Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012 vs 1 ft. 6 in. (0.455 m) on the Zodiac Classic Mark 2C ST 2012 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Zodiac Classic Mark 2C ST 2012 if your priority is putting more people on the water — it handles 6 passengers and at 12,5 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Fastroller 325 ACTI-V INT-L 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
