When choosing the mooring ropes, it’s essential to consider strength, durability, and resistance to the harsh marine environment. The most commonly recommended types of rope for mooring are polyester ropes and nylon ropes. Polyester preferred for its excellent resistance to UV rays, water absorption, and low stretch properties. Making it ideal for maintaining tension on mooring lines. Nylon, on the other hand, offers excellent shock absorption and strength, which is ideal for boats and ships exposed to varying forces. Additionally, ropes with braided or twisted constructions often chosen for their flexibility and ease of handling. Our engineers will explain in detail the types, uses and materials of mooring lines.
