When two boats share the same hull type — in this case both the Zodiac Cadet Roll Up 200 2010 and the Zodiac Zoom SP 400 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?
Size is the most obvious dividing line here. The Zodiac Zoom SP 400 ALU 2013 measures 13,1 feet overall (2013), giving it roughly 6,5 additional feet of deck space compared to the Zodiac Cadet Roll Up 200 2010 at 6,6 feet (2010). Weight tells a clearer story for trailering families: the Zodiac Zoom SP 400 ALU 2013 tips the scales at 187 lbs — 138 lbs less than the Zodiac Cadet Roll Up 200 2010 at 49 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 25 hp, the Zodiac Zoom SP 400 ALU 2013 has a 21-hp advantage over the Zodiac Cadet Roll Up 200 2010's 4-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 Zoom SP 400 ALU 2013 is rated for 7 passengers, while the Zodiac Cadet Roll Up 200 2010 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom SP 400 ALU 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Zoom SP 400 ALU 2013 comes in at 8 lbs per hp versus 12 lbs per hp for the Zodiac Cadet Roll Up 200 2010. 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 Cadet Roll Up 200 2010 has a documented top speed of 7 mph. Speed data wasn't available for the other model.
Bottom line: Choose the Zodiac Zoom SP 400 ALU 2013 if your priority is putting more people on the water — it handles 7 passengers and at 13,1 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Roll Up 200 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
