cap

The Sailor's Word-Book

A strong thick block of wood having two large holes through it, the one square, the other round, used to confine two masts together, when one is erected at the head of the other, in order to lengthen it. The principal caps of a ship are those of the lower masts, which are fitted with a strong eye-bolt on each side, wherein to hook the block by which the top-mast is drawn up through the cap. In the same manner as the top mast slides up through the cap of the lower mast, the topgallant-mast slides up through the cap of the top-masts. When made of iron the cap used to be called a crance.


♦ To cap a mast-head is placing tarpaulin guards against weather. The term is applied to any covering such as lead put over iron bolts to prevent corrosion by sea-water, canvas covers over the ends of rigging, &c. &c. Also, pieces of oak laid on the upper blocks on which a vessel is built, to receive the keel. They are split out for the addition of the false keel, and therefore should be of the most free-grained timber. Also, the coating which guards the top of a quill tube. Also, the percussion priming for fire-arms.

♦ Cap-a-pied, armed from head to foot.
