Zodiac disputes Canadian study on back safety
By IBI Magazine
Zodiac North America has questioned the scientific validity of a Canadian study that investigated the effect of Zodiac Hurricanes on the backs of operators in rough seas. Weir Canada Inc has done a study for the Canadian Coast Guard to determine potential health problems associated with the Zodiac Hurricane 733. The Canadian Coast Guard owns about 100 of the 7.3m (24ft) boats, known as RHIBs, often used for rescue in poor weather. They are also common boats in navies and other coast guards around the world. The 733 series is also for sale on the recreational boating market.
The C$85,000 study found that the up-and-down vibrations during travel through heavy seas sometimes exceeded health thresholds established for operators of land vehicles, the only comparable standard available.
An engineer with Zodiac Hurricane Technologies Inc, however, told Canada.com that the study required operators to sit firmly in their seats during the bumpy rides, contrary to Zodiac's advice to customers and to the Coast Guard's own instructions to its sailors.
"The scientific validity of the study that the Coast Guard did on the boats is questionable because the configuration that they tested is not the configuration that people actually use when they're driving the boats," said Zodiac's John Garfitt. "In fact, they should not keep their bums firmly planted in their seats because that will result in back injuries — it's just common sense."
The Canadian Coast Guard ordered the study after one of its sailors won a workers' compensation claim for hip problems he alleged were aggravated by the pounding of an RHIB.
Garfitt told the news site these boats often endure conditions other vessels cannot manage. "RHIBs are the boats that go out in the worst weather, under the worst conditions, when everything else is back at the dock," he said. "There's an onus on the people driving them to use common sense. You need to be trained and you need to operate them in a sensible way."
Garfitt said the company is not aware of any claims about back injuries linked to Zodiac RHIBs.

Wow!!!! Interesting, I am waiting to get 2 new hips, been on commercial RIBS 25 years, wonder how my hips went?? I have been told that it was the banging and shock due to my job, I have tested and operated all types of RIBS and I never sit down unless I have no choice, so thats that theory out the window, they are extreme and used in extreme conditions in a commercial factor, part of the jobs risk factor I think, cheers Dog
