TENDING SHIP AT ANCHOR 297 <
18 Suppose in a strong wind or tide she "yawed" about, frequently
breaking her sheer;, what would you do?
Have a man at the wheel, and steer her as if under way.
19 What is the best position to have the shackles when you1 are moored
with two anchors in a tideway?
They should be where they would be handy to get at in the event
of having to unshackle for the purpose of clearing hawse. Close abaft
the compressor or windlass would be a good place. There would then
not be much cable to pass round.
20. Why are ships moored with two anchors^
Because when moored with two anchors placed in opposite directions
they do not cover so much ground when swinging at each turn of the
tide. They would ride to one anchor on the flood, turn ronnd practically
in their own length, and ride to the other on the ebb
21. In what direction should the anchors lie when moored in a tideway?
In the direction of the ebb and flow of the tide The one to which
the vessel was riding should be a little on one bow, and the other one
fine on the opposite quarter.
22. How often does a vessel swing when she is anchored or moored in a
tideway?
She swings at every turn of the tide in moderate weather. That is
at intervals which will average about 6J hours.
23. Does it matter which way she swings?
Yes. She must always swing round on the same side of her two
anchors. If she does not, she is liable to get turns in her cables.
24. What would you do to ensure her swinging the right way?
Give her a sheer with the helm just before slack water. The new
tide would then catch her on the quarter" and swing her round in the
same direction in which I had sheered her.
25. Suppose through failing to tend her, or for any other reason she
swung round the wrong wjay; what would happen?
The first swing would cause a cross in the cables, the second swing
would produce an elbow, and if she swung round the wrong way three
times there would be a round turn.
