When two boats share the same hull type — in this case both the Zodiac Bayrunner Pro Series 2011 and the Zodiac Cadet RIB 340 2011 are inflatable rigid designs with fiberglass 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 Bayrunner Pro Series 2011 at 13,8 ft versus Zodiac Cadet RIB 340 2011 at 11,2 ft. At 82 lbs and 172 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.
The Zodiac Cadet RIB 340 2011 tops out at 25 hp. Engine specs for the Zodiac Bayrunner Pro Series 2011 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Zodiac Cadet RIB 340 2011 is rated for 5 passengers, while the Zodiac Bayrunner Pro Series 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Cadet RIB 340 2011 could be the deciding factor.
The Zodiac Cadet RIB 340 2011 has a documented top speed of 30 mph. Speed data wasn't available for the other model.
Bottom line: Choose the Zodiac Cadet RIB 340 2011 if your priority is putting more people on the water — it handles 5 passengers and at 11,2 ft it has the deck room to back that rating up comfortably. The Zodiac Bayrunner Pro Series 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
