Matching a inflatable non rigid Zodiac Cadet 340 Solid 2013 against a inflatable rigid Zodiac Zoom 400 SR 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Zodiac Cadet 340 Solid 2013 at 11,2 ft versus Zodiac Zoom 400 SR 2008 at 13,0 ft. Weight tells a clearer story for trailering families: the Zodiac Zoom 400 SR 2008 tips the scales at 254 lbs — 139 lbs less than the Zodiac Cadet 340 Solid 2013 at 115 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 — 20 hp for the Zodiac Cadet 340 Solid 2013 and 30 hp for the Zodiac Zoom 400 SR 2008. 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 2008 is rated for 7 passengers, while the Zodiac Cadet 340 Solid 2013 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 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet 340 Solid 2013 comes in at 6 lbs per hp versus 9 lbs per hp for the Zodiac Zoom 400 SR 2008. 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 340 Solid 2013 has a documented top speed of 28 mph. Speed data wasn't available for the other model.
The Zodiac Cadet 340 Solid 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Zoom 400 SR 2008 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 400 SR 2008 if your priority is putting more people on the water — it handles 7 passengers and at 13,0 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet 340 Solid 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
