Ocean Classic Fenders - Series H heavy duty is the perfect fender for sailboats and motorboats. The fender is made of plasticized PVC and is available in 8 different sizes and two traditional color options. It has a consistent thickness throughout, is produced in one piece, and is UV-protected. The fender is inflated with an air pressure of 0.15 bar at 20°C, and it is important to be cautious and not inflate the fender too much, as air expands in heat and the fender may become misshapen.
