Sail board wishbone end connection - has two solid open ended ferrules allowing water flow to and from tubes

摘要

The end connector for the two wishbone tubes of a sailboard has two solid ferrules, open at both ends. These receive the tubes, at the same time allowing liquid to pass from the outside to inside the tubes and vice-versa. It is possible to fix the tubes to prevent movement relative to the ferrules. The material used for the connector can be pliable or rigid. The connector forms the wishbone front apex and it also includes an attachment to engage the mast. The connector can also have a rope passage.
