Rooster's Zero is a 12 braided 'hollow' rope made from quality UMHPE fibres before being treated to reduce any stretch to a minimum.
The heat treatment also makes this line maintain its shape in cleats, which is an unusual quality in many Dynema lines. We cut our travellers to 3.3m so that in the unlikely event that it were to start to show wear, you would be able to end for end the rope. The 3.3m also gives you enough of a handle to tension - although with so little stretch, you might want to tension your traveller before you put your rudder on.
