M Rig Max’s top benefit is minimal creep ideal for standing rigging and steering lines. Add an MGP cover or light weight chafe cover for high wear applications such as life lines.

M-RIG MAX – SYNTHETIC FIBRE STANDING RIGGING FOR THE CRUISER / RACER M-Rig Max uses Dyneema’s DM20 Max Technology yarn. DM20 exhibits zero creep meaning that it lends itself for use as super lightweight standing rigging. Every kilogram saved aloft equates to a 5-7kg saving at the keel, as well as reduced pitching in a head sea. Marlow’s M-Rig Max brings creep free fibre standing rigging within reach of everyday yachtsmen. Traditionally, fibre standing rigging has been incredibly expensive thanks to the use of Zylon ® (PBO) in a custom-made cable configuration. M-Rig Max uses DM20 and Marlow’s Max Pre-Stretching technology to produce a rope that is available to any rigger on a reel.

1. Measure the rig 2. Cut M-Rig Max to length

3. Use simple locking D12 Splice with lashing thimbles 4. Secure and tension using Marlow Lashline (page 14)

The lower modulus of Dyneema ® DM20 means that even with Marlow’s Max Pre-Stretching, to match the stretch exhibited by wire (as measured by mm/mm/1000kg) a larger diameter will be required. The table also demonstrates that not only is M-Rig Max lighter, it is also 5x stronger than wire for a given stretch factor. Significant strength advantage means that if the initial elastic elongation experienced by Dyneema can be managed (see page 8), a smaller diameter of M-Rig Max can be specified.

The choice of M-Rig Max diameter is a balance between ultimate strength and manageable elongation.
