When two boats share the same hull type — in this case both the Zodiac Classic Mark 2 ST 2012 and the Zodiac Zoom SP 450 ALU 2013 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 Classic Mark 2 ST 2012 at 13,8 ft versus Zodiac Zoom SP 450 ALU 2013 at 14,8 ft. At 183 lbs and 212 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.
Both boats share a closely matched power ceiling — 40 hp for the Zodiac Classic Mark 2 ST 2012 and 40 hp for the Zodiac Zoom SP 450 ALU 2013. 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 Zoom SP 450 ALU 2013 is rated for 8 passengers, while the Zodiac Classic Mark 2 ST 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom SP 450 ALU 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Classic Mark 2 ST 2012 comes in at 5 lbs per hp versus 5 lbs per hp for the Zodiac Zoom SP 450 ALU 2013. 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.
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 Zoom SP 450 ALU 2013 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 Zoom SP 450 ALU 2013 if your priority is putting more people on the water — it handles 8 passengers and at 14,8 ft it has the deck room to back that rating up comfortably. The Zodiac Classic Mark 2 ST 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
