1 A name given originally to the lower end of the principal stays of a mast in a square-rigged ship, but later to the rope, with a deadeye in its end, to which the stay was secured at its lower end. Thus, the collar of the forestay was the short length of rope attached to the stem of the ship to which the stay was set up and secured. See also mouse.
2 The eye in the upper end of a stay, or in the bight of the shrouds, which was threaded over the masthead before being set up taut to hold the mast secure.
3 The neck of a ringbolt.
