Running Rigging

Running rigging of a sailing vessel is used for raising, lowering, shaping and controlling the sails, as opposed to the standing rigging, which supports the mast. We supply a comprehensive range of ropes from Marlow, with more than 200 years of experience, covering the spectrum of running rigging from cruising, mooring and racing. Our experts calculate the load to recommend the appropriate product.


Our rigging team produce all types of splices in house for your specific application. Some in-mast furling systems require an endless splice for flawless operation. A knot reduces the breaking load of a line by up to 50%. A splice reduces the breaking load by 5%, maintaining 95% of the breaking load.


For endless furling line we reccomend the MGP Furler 50, with snakeskin pattern allows easy end-to-end splicing with no diameter increase. Vectran or Technora cover blended with polyester ensures heat and abrasion resistance. MGP Furler has a sacrificial polypropylene core as standard, but can be up graded to a D12 core for higher load furling systems.


The halyard hoists the sail, and if on a furling unit, it stays there for the season. It is important that the halyard does not stretch, as this offers consistent sail shape. We recommend one of the aft halyards is extra long for a MOB situation.


The sheet on a sail controls the angle of the sail to the wind. Malleability of the material is crucial when working on the winches.


PS12 is a soft, yet strong 12 strand Polyester rope which has been designed to be easily spliced for halyard tails and lazy jacks.


The length of bow and stern lines should equal two-thirds of your boat's overall length. Spring lines should be approximately the same length as your boat. Your mooring line should have 3mm of diameter for every 3m of boat with a minimum size of 10mm.

The Blue Ocean Dockline, made from 100% recycled plastic bottles is exclusive to Marlow's Mooring Series this year.
