218 NICHOLLS'S SEAMANSHIP AND. NAUTICAL KNOWLEDGE
16. A green light overhauls you on your port side and then attempts to
cross ahead. What would you do? ' s
As she is the overtaking vessel she must keep clear of me until
she is finally past and clear. (Art. 24). I must keep my course and speed.
{Art. 21.) At the same time I must observe the footnote to Article 21,'
and if she gets too near me to avoid collision by her own action I should
also take action as would best help her to do so. ' Probably that would .
be "full speed astern," 3 short blasts. Look out for anything that
might be coming up behind me.
17. You are in a steam vessel and you sight the red light of a sailing
vessel on your port bow. What would you do?
We are passing ships and will most likely go clear of each other.
If she was to windward of me and was in ballast, or if it was blowing
hard, she might be sagging down to leeward towards me. I should
watch her bearing carefully and if it did not change appreciably should
alter my course to starboard to get out of her way. Should give her
1 short blast. (See Arts. 27, 28, and 29 )
