3' Diameter fenders are the solution for larger yachts that require even larger fenders. Recommended for yachts ranging from 100' to 200', these fenders finally allow larger yachts to carry the size of fender that they actually need to protect their yacht. Up to 10X stronger than a standard vinyl fender, but can easily be deflated for storage anywhere. All 3' diameter fenders have multiple "D" rings on each end and a load spreading kit is required when using 3' diameter fenders. Not using all three d-rings will void the warranty. We recommend utilizing our 1/2" Load Spreader kit.
