traffic-congested water is

even more challenging. Specifically, due to the presence of many vessels

the vicinity, a repeated risk of collision exists. Any action to avoid a close

quarter situation

another vessel is limited due to the existence of a

third vessel or proximity of shoal water or other fixed structure, or where

such a situation is expected to arise.

Therefore,

w

hen the vessel is in congested water upon receiving the report from the

OOW, the Master above must confirm the situation and increase officers or

ratings for lookout as required. He shall take

the command of the

vessel.
