Racing-cruising sail : spinnaker
OUTSIDER SAILS
Nylon is mainly used for the sails of bearing because it is light, solid and cheap. It is a a little elastic fiber, which makes it possible to absorb the peaks of load and makes the sails more stable and thus easier to make carry and to regulate.
The Polyester appeared recently in the manufacture of the spis because it lengthens less than Nylon - especially when it is wet - but its design and its manufacture require more experiment. A Polyester spinnaker transmits more loads to gréement, in particular when it opera hat or is reinflated. Nylon is more sensitive to UV and the chemicals: it should NEVER be washed with Javel or in a swimming pool!!
