The Zodiac Cadet Fastroller 340 FR Acti-V INT-L 2008 vs Zodiac Zoom 400 SR 2006 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.

On paper these two are close siblings in the size department — Zodiac Cadet Fastroller 340 FR Acti-V INT-L 2008 at 11,0 ft versus Zodiac Zoom 400 SR 2006 at 13,0 ft. Weight tells a clearer story for trailering families: the Zodiac Zoom 400 SR 2006 tips the scales at 254 lbs — 175 lbs less than the Zodiac Cadet Fastroller 340 FR Acti-V INT-L 2008 at 79 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.

Both boats share a closely matched power ceiling — 15 hp for the Zodiac Cadet Fastroller 340 FR Acti-V INT-L 2008 and 30 hp for the Zodiac Zoom 400 SR 2006. 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 400 SR 2006 is rated for 7 passengers, while the Zodiac Cadet Fastroller 340 FR Acti-V INT-L 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom 400 SR 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet Fastroller 340 FR Acti-V INT-L 2008 comes in at 5 lbs per hp versus 9 lbs per hp for the Zodiac Zoom 400 SR 2006. 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 340 FR Acti-V INT-L 2008 has a documented top speed of 26 mph. Speed data wasn't available for the other model.
