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)
