Abstract
In a jib sail system, roller-furling and interchangeability of jibs is provided by utilizing a rotatable, slotted stay member, preferably aerodynamically shaped, and by providing at the top of the stay member a ratchet-latching mechanism so that tension on the jib halyard can be released thereby facilitating a swivel coupling attachment of the halyard to the head of the jib.
