Marlowbraid is probably the most well known and respected line in the Marlow Ropes range.

Marlow have been producing this 100% polyester braided line for decades, and it has become a firm favourite for cruising yachts worldwide.

Marlowbraid is an excellent, relatively low stretch, hard wearing solution for most running rigging applications
e.g sheets, halyards, control lines, guys, reef lines, tack lines, vangs, down/outhauls, furling lines, runner tails and preventers.

Marlowbraid Specification:
Cover: Durable 16plait polyester
Core: twisted loose lay 3-strand construction that delivers minimum achievable stretch (approximately 4-5%) without dyneema content

Marlowbraid Facts, Features and Plus Factors:

  • Twisted 3-strand core delivers marginally less stretch than braid on braid construction
  • Tendency to flatten under load e.g. around winches, due to the loose laid core
  • Excellent abrasion resistance
  • Good UV stability
  • Spliceable
  • Very high load capacity for 100% polyester halyard
  • Available in: white with black, blue or yellow coding; full colour Natural (Classic)
Diameter 6mm 8mm 10mm 12mm 14mm 16mm
Weight p100m 2.68kg 4.45kg 7.3kg 10.0kg 14.5kg 19.0kg

Jimmy Green Marlowbraid Running Rigging Size Guide

The Jimmy Green Rigging Team have produced this line diameter chart from Marlow's own recommendations to assist you in specifying your Marlowbraid for a halyard, sheet or control line.
Use a combination of your yacht length and the appropriate sail area to interpret the table and determine the closest match to your requirement.

Marlow generally recommend reducing the line diameter by one size if you are considering a halyard with a dyneema core.
