Abstract: A jib furler halyard top fitting has a body for coupling to a top end of an extruded member that longitudinally receives a stay and a main portion of a halyard of a marine vessel such that the extruded member is rotatable about the stay. The body of the fitting has a passage to receive the stay. A first sheave supported on the body has a perimeter edge aligned with the main portion of the halyard extending through the extruded member. A second sheave supported on the body has a perimeter edge aligned with an end section of the halyard coupled to the top of the jib. A third sheave supported on the body has a perimeter edge including portions aligned with the first and second sheaves respectively such that the halyard remains tangential with adjacent sheaves along a length of the halyard received through the fitting.
