Polyester 3-Strand Twisted Rope, White 6–38 mm – Durable & Weather-Resistant (Good Quality)

This all-purpose polyester twisted rope (3-strand) combines strength, reliability, and ease of handling, making it a top choice for numerous marine tasks. It is made from 100% high-tenacity polyester – a material known for its resistance to UV rays, abrasion, and heavy loads. The rope comes in white with interwoven colored tracer yarns (red and blue), providing good visibility and a clear twist pattern along its length. Being polyester, the rope sinks in water (its fibers are denser than water), which is advantageous for anchor lines and mooring where floating ropes could cause entanglement or hazards. Over time, this rope maintains its flexibility and does not deform or stiffen, thanks to its quality construction and balanced 3-strand lay.

Applications: It is perfect for mooring lines, keeping your boat securely docked – polyester’s slight stretch absorbs sudden loads and its abrasion resistance withstands chafing on cleats and pilings. It’s also ideal as an anchor rope (rode), ensuring a reliable connection to your anchor with minimal stretch for a firm hold. You can use this rope for towing dinghies or other vessels, and for general onboard purposes where a strong, dependable line is needed. Polyester 3-strand is also favored for certain sailing rigging tasks on smaller sailboats when a combination of moderate elasticity and high strength is required (for example, as a sheet or an all-purpose halyard on cruising boats).

Size Recommendations (Diameter vs. Boat Size): Choose the rope diameter based on your boat’s size and the intended use:

• 6–8 mm – Suited for small craft, inflatables, and dinghies up to ~4–5 m, or as utility lines (fender lines, flag halyards, etc.).
• 10–12 mm – A versatile size for medium boats around 5–7 m. Commonly used for mooring and anchor lines on small yachts and motorboats, as well as light towing of smaller vessels.
• 14–16 mm – A robust diameter for boats roughly 8–10 m long. Preferred for primary mooring lines on mid-sized yachts, heavier anchor rodes, and towing of moderate-sized craft.
• 18–22 mm – Thick rope for larger yachts about 10–15 m. Handles very high loads – an excellent choice for main dock lines on heavy yachts and for deep-water anchoring on big vessels.
• 24 mm and above – Specialized diameter for very large boats (over ~15–18 m) or commercial applications. Used when extremely high load capacity is required and safety is paramount.

Always match the rope size to your vessel’s requirements for load and safety. This polyester rope offers good quality at an affordable price, ensuring years of reliable service with minimal upkeep (it won’t rot or mildew and stands up to saltwater exposure).
