CPI Marine is the only RIB collar manufacturer offering removable air bladders as an alternative to traditional designs that use multiple air chambers separated by internal baffles. With our patented air bladder system, each chamber has its own removable, repairable and replaceable air bladder (similar to an inner tube in a car or truck tire). The bladders are made from a urethane film material for optimum durability. The bladder design allows for quick, easy and inexpensive repairs in case of a puncture to the outer tube. The bladder can be deflated and extracted from the tube and replaced by a new one in less than half an hour - without pulling the boat out of the water. 

Our traditional baffled tube collars can be retrofitted with bladders in the future, in the event of a puncture or damage to one or more of the internal air chambers.
