3 strand polyester 4mm rope, also known as 3 strand laid rope or braided polyester rope, is a suitable option for certain applications in dinghy sailing, but with limitations compared to 16 plait braid rope. 

Here's a breakdown:

  • Material:
    • Constructed with three strands of twisted polyester fibers.
    • Offers a good balance of strength and affordability compared to more complex braids.
  • Properties:
    • Moderate strength: While suitable for light loads, it may not be ideal for critical applications requiring maximum strength.
    • Higher stretch: Elongates more under tension compared to 16 plait rope, potentially affecting sail control and line precision.
    • Easier to handle: The simple 3 strand construction makes it easier to knot and splice compared to 16 plait.
  • Applications in dinghy sailing (limited):
    • Control lines: Where stretch is less of an issue, where splicing is desirable in lighter lines, and where good grip is required in cleats due to its more “knobbly” surface.

Important considerations:

  • Strength limitations: For critical applications like halyards or sheets directly controlling sails, 16 plait rope is generally recommended due to its superior strength and lower stretch.
  • Safety: Always prioritize using ropes with adequate strength for the intended purpose, especially in dinghy sailing where weather conditions can change rapidly.
