The person responsible for developing the CZ7 concept within Zodiac is Gary Durnan. Here is the contact information:
ZHT - Marine Division
He should be able to provide the info, or direct you to the video production company for details.
There are many manufacturers of RIBs in America, and many foreign manufacturers are represented here as well. RIB International published a directory of US manufacturers in one of their issues (see http://www.ribmagazine.com/index.htm
), and a partial list can be found at http://www.allinflatables.com/suppliers/index.html
I share your amazement that more people are not using RIBs in the US, so I guess the only thing we can do is own as many of them as possible!
