GRAVING, oeuvres de marée, the act of cleaning a ship’s bottom when she is laid aground during the recess of the tide. See the article Breaming, where this operation is particularly explained.
GRIPES, haubans de chaloupe, a machine formed by an assemblage of ropes, hooks, and dead-eyes, and used to secure the boats upon the deck of a ship at sea, and prevent them from being shaken by the labouring of the vessel. The hooks, which are fastened at their ends, are fixed in ring-bolts in the deck on each side of the boat; whence, passing over her middle and extremities, they are extended by means of the dead-eyes, so as to render the boats as firm and secure as possible.
Griping, ardent, the inclination of a ship to run to windward of her course, particularly when she sails with the wind on her beam or quarter. This effect is partly occasioned by the shock of the waves that strike the ship perpetually on the weather-quarter, and force the stern to leeward; but chiefly by the arrangement of the sails, which disposes the ship continually to edge to windward, while in this situation of sailing.
GROMMET, daillot, a sort of small wreath, formed of a strand of rope, and used to fasten the upper edge of a stay-sail to its respective stay, in different places. By means of the grommets, the sail is accordingly hoisted or lowered, i. e. drawn up or down upon its stay, in the same manner as a curtain is extended or drawn along upon its rod, by the assistance of rings. See also the article Hank.
GROUNDING, the act of laying a ship ashore, in order to bream or repair her. It is also applied to running aground accidentally when under sail, or driving in a tempest.
GROUND-TACKLE, amarrages, a general name given to all sorts of ropes and furniture which belong to the anchors, or which are employed in mooring, or otherwise securing a ship in a road or harbour; as cables, hausers, tow-lines, warps, and buoy-ropes.
GROWING, implies the direction of the cable from the ship towards the anchors; as, the cable grows on the starboard-bow, i. e. stretches out forwards on the starboard, or right side.
GUARD-BOAT, a boat appointed to row the rounds amongst the ships of war which are laid up in any harbour, &c. to observe that their officers keep a good look-out, calling to the guard-boat as she passes, and not suffering her crew to come aboard, without having previously communicated: the watch-word of the night.
GUARD-IRONS, certain curved or arched bars of iron placed over the ornamental figures, on a ship’s head or quarter, to defend them from the impression of some other ship when they lie close to, or rub against each other.
GUARD-SHIP, a vessel of war appointed to superintend the marine affairs in a harbour or river, and to see that the ships, which are not commissioned, have their proper watch kept duly, by sending her guard-boats around them every night: she is also to receive seamen who are impressed in the time of war.
