Name the device pictured and describe 

 one or more methods of engaging the 

 motor or engine drive to heave up the 

 anchor chain. 



What precautions must be observed 

 by a vessel anchored in an exposed 

 roadstead? 



Standing anchor watch in a fog, what 

 signal can you give when a vessel ap- 

 proaches so close that collision seems 

 possible? 



If an anchor drags in a clay bottom, 

 how may its holding power be affected? 



Describe the advantage of detachable 

 links over U-shaped connecting shackles 

 in anchor cable. 



How do crosses, elbows, or round 

 turns get into cables? 



Where would you make an anchor 

 buoy-rope fast? 



How is the size of a chain cable 

 measured? 



Name the mooring lines in the sketch 

 below. 



Why is it advisable to have a man 

 stationed at the windlass to handle the 

 anchors, if necessary, when proceeding 

 in constricted or congested waters? 



Describe the use of the anchor in 

 turning a ship. 



What would you do if, riding to a 

 single anchor, you found you were 

 dragging? 



A vessel 450 feet long anchors with 

 105 fathoms of chain, and with 20 

 fathoms from her hawse pipe to the 

 bottom. What diameter circle will she 

 describe as she swings to the tide? 



What is a lee tide? What is a 

 weather tide? 



Anchored in an exposed roadstead, 

 what precautions should you observe? 



When a vessel is moored to two 

 anchors, what is the most advantageous 

 position for the cable shackles, or de- 

 tachable links, in event of a foul hawse? 



Why are ships moored with two 

 anchors? 



What is the length of a shot of chain? 



In a congested anchorage, what pre- 

 cautions are necessary at slack water 

 when the tide is changing? 



Describe how you might carry out an 

 anchor using ship's lifeboats. 



On a vessel fitted with cowl type 

 ventilators it is necessary to trim the 

 ventilators at night with only one 

 standby man available. The ventilators 

 are stiff so that using the handles he 

 could not trim them alone. Using a 

 pinch bar through the handle would 

 break off the handle. How could he trim 

 the vent alone? (If you wish, illustrate 

 the answer by a sketch) . 



You are left in charge of a vessel at 

 night alongside of a dock in New York 

 Harbor, and you discover that a serious 

 fire has started on your vessel. Explain 

 in detail what you would do. 



A mate standing on the port wing 

 of the bridge, 30 feet from the vessel's 

 center line, sights a vessel across the 

 jackstaff, 200 feet forward of the 

 bridge, and assumes the vessel is dead 

 ahead. How much is he in error? 



What is the best position for deter- 

 mining the relative bearing of an ob- 

 ject seen from the bridge?
