AERÉ 4' diameter fenders are the solution for megayachts that require even larger fenders. Recommended for yachts larger than 200', these fenders finally allow superyachts 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. 4' x 20' fenders only available in black or gray. All 4' diameter fenders have multiple "D" rings on each end and a load spreading kit is required when using 4' diameter fenders. Not using all three d-rings will void the warranty. We recommend utilizing our 5/8" Load Spreader kit.
