Blue End Fenders Heavy-duty fenders built for large boats. Although originally built for commercial vessels - barges, ships and ferries, recreational yachtsmen find these fenders ideal for large yawls, schooners, motor sailers, racer/cruisers, etc. The material is resistant to sunlight, seawater, mineral oils, cleaning agents and common solvents. High abrasion resistance. No cords or linings to cause high internal air pressure under heavy fendering conditions. The temperature range of -68 F to +140 F allow use in arctic or tropical conditions. Fenders do not qualify for free freight.
