The Zodiac Cadet Fastroller 285 ACTI-V 2010 vs Zodiac Zoom 310 S 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Zodiac Cadet Fastroller 285 ACTI-V 2010 measures 9,3 feet overall (2010), giving it roughly 8,3 additional feet of deck space compared to the Zodiac Zoom 310 S 2007 at 1,0 feet (2007). At 77 lbs and 84 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 — 8 hp for the Zodiac Cadet Fastroller 285 ACTI-V 2010 and 6 hp for the Zodiac Zoom 310 S 2007. 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.
Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet Fastroller 285 ACTI-V 2010 comes in at 10 lbs per hp versus 14 lbs per hp for the Zodiac Zoom 310 S 2007. 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 Fastroller 285 ACTI-V 2010 has a documented top speed of 20 mph. Speed data wasn't available for the other model.
Bottom line: The Zodiac Cadet Fastroller 285 ACTI-V 2010 at 9,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Zoom 310 S 2007 at 1,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
