Thought I would add this as a new thread because like me, I found many others were trying to get replacement collars.
Force 4 are the very popular New Zealand
made RIB's with detachable inflatable
collars. After 10 years the collar on mine was reaching the end of its usable life but when I tried to replace it I was disappointed to discover that Force 4 no longer existed. I am pleased to say that Feral Inflatables in South Africa
now make replacement collars and because of the slide on design they can be shipped any where in the world. They are of very high quality with thermo welded seams using the same PVC as the original. Currently only the 3.1m is readily available but other sizes can be made.
