When preparing to anchor, it is necessary to take to the forecastle a hammer, an oil can and some goggles. Before going to the forecastle, ask the engine room for power and water on deck. First, take off the covers from the hawse pipes and clear the spurling pipes. Then, make sure that the windlass is out of gear and the brakes are on. Next, turn the windlass over slowly. While you are doing this, oil all the moving parts. On a steam windlass, the drain cocks must be opened and the water drained off before the cocks are closed again. After seeing that the gears are free to engage, put the windlass into gear. Then remove the devil's claw and the compressor bar. On receiving the order to lower away, lower the anchor until it is clear of the hawse pipe. When you are sure that the weight of the anchor is held by the brake, take the windlass out of gear). When the order to let go the anchor is received, release the brake. As each shackle (27.5 metres) goes out, the forecastle bell is rung (1 ring for 1 shackle, 2 rings for 2 shackles et). When the anchor reaches the bottom, hoist the anchor ball or anchor lights. When enough cable has been paid out, apply the brake and put on the compressor bar. Then inform the engine room that power and water are finished with. Finally return all the gear. 1、When preparing to anchor, it is necessary to take to the forecastle a hammer, an oil can and some goggles. The goggle is _______.
