The mixed braiding of the core combines both the resistance of Dyneema® and lightness of Polypropylene. The Dyneema® guarantees a very low elongation and the water-repellent Polypropylene avoids weight gain caused by water infiltration. The advantage of mixed braiding is that it enables you to cut costs on ropes in order to benefit from good mechanical properties for an affordable price. The Polyester cover guarantees the rope a long life by protecting it from abrasion relative to chafing.
We recommend the Punch rope for your halyards. You can also use it for your genoa or mainsail halyards. Used as a boom downhaul control line or reefing line, it improves the precision of settings.
How to choose the right diameter:
First, consider diameter suitable with your clutches and cleats. Without adding a chafe sleeve, the minimum diameter that is recommended for a standard clutch may slip once the rope is under load.
We suggest that you add a Technora Polyester type chafe sleeve at the passage point where your rope passes through clutches. It increases the grip, avoids slipping effect, increases the lifespan of your rope by protecting it from chafing caused by the clutch.
To estimate the breaking load of your halyard (in kg):– Genoa surface x 80
– Main sail surface x 100
– Spinnaker surface x 30
To estimate the length of your halyard:
– Genoa = Mast length x 3
– Spinnaker = Mast length x 3
– Main = Mast length x 2.5
The specified load is the breaking load. Consider half of the working load.”
