Made by Marlow in England.

This classic 3 strand line of Polyester is manufactured using the highest quality materials and specifications to produce a rope with the perfect balance of flexibility and firmness.  

3 Strand has the advantage of being very easy to splice.

Breaking Load: 4mm = 529kg

BENEFITS:

• Flexible & easily handled
• Good abrasion resistance
• Good chemical resistance
• Good strength
• Good UV resistance
• No strength loss when wet
• Very easily spliced
• Zero shrinkage

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.
