ABSTRACT:
In the depicted embodiment, the jib shackle comprises a two-section body having converging arms extending therefrom. The sections of the body are relatively rotatable, about the axis of the body, to move the converging limbs into and out of proximity with each other. When the limbs are put into proximity, they define a closed loop with the body, and when moved out of proximity, open the loop. Ends of the body are apertured to receive therethrough a line (rope, hawser, etc.) which may be knotted, within the loop, to prevent its withdrawal from the shackle. Ends of the limbs which are remote from the body have complementary configurations which cause such ends mutually to nest with each other, upon being closed upon each other, to define the surfaces of the loop with substantially no discontinuities or abrupt edges. The novel shackle is formed of rigid plastic, hence on shipboard use it will not mar or otherwise abuse wooden or fiberglass boat surfaces.
