Section II – Conduct of vessels in sight of one another
Rule 16: Action by give-way vessel
Every vessel which is directed to keep out of the way of another vessel shall, so far as possible, take early and substantial action to keep well clear.
Meaning: Give way vessels should take action well in time, estimate the speed of approach between the two vessels, estimate the approximate time interval and then take action, do
not take a late action, since this would make the stand on vessel apprehensive and she may then take an action which would be detrimental to both vessels.
