Elongation is based on figures taken from tests across the diameter range, to produce an average figure.



Sheets are a line used to control the movable clews of a sail. We have many options for sheets on board for dinghy sailors through to Grand Prix race boats.



Polyester has a specific gravity of 1.38 which means it will not float. Polyester has no strength loss when wet, it is flexible and has good abrasion resistance. Polyester fibres also have good resistance to chemicals and have a melting point of 295°C.


Dyneema®, the world’s strongest fiber™, is respected as the premium brand for Ultra-High Molecular Weight Polyethylene (UHMwPE). We offer many ropes produced using Dyneema® fibres including single braids and double braids. We use Dyneema® SK99, Dyneema® SK78 and Dyneema® DM20 fibres to produce our ropes. These different types of Dyneema® fibre are used to produce ropes for specific applications.
