Open sea situations
SITUATION 01
Q. You are the OOW of a power-driven vessel and you see these lights. What do the lights indicate to you?
A. A power-driven vessel probably 50m or more in length, port side on, underway.
Q. You see this vessel four points on the starboard bow. What action will you take?
A. I will take a series of compass bearings of an approaching vessel and, if the compass bearing does not change appreciably, then the risk of collision exists.
Q. The bearing is constant and range decreasing. What action will you take now?
A. As per Rule 15, my vessel is the give-way vessel and the other is to stand on. I will sound one short blast and make a broad alteration of the course to starboard and pass well clear of the other vessel.
SITUATION 02
Q. You are the OOW of a power-driven vessel. You see these lights. What do the lights indicate to you?
A. A power-driven vessel less than 50m in length, underway, end-on.
Q. You see this vessel right ahead. What action will you take?
A. As per Rule 14, my vessel is the give-way vessel and the other is also the give-way vessel. I will sound one short blast and then make a broad alteration of the course to starboard and pass well clear of the other vessel.
SITUATION 03
Q. You are the OOW of a power-driven vessel. You see these lights. What do the lights indicate to you?
A. A power-driven vessel probably 50m or more in length, underway, seen from the starboard side.
Q. You see this vessel three points on the port bow. What action will you take?
A. I will take a series of compass bearings of an approaching vessel and, if the compass bearing does not change appreciably, then the risk of collision exists.
Q. The bearing is constant and range decreasing. What action will you take now?
A. As per Rule 15 my vessel is the stand-on vessel and other vessel is the give-way vessel. I will maintain my course and speed and stand on with caution and continue to monitor the situation.
Q. This vessel is not taking any action and getting closer. What will you do now?
A. I will sound at least five short and rapid blasts to draw her attention. At night I will also use an Aldis lamp to draw her attention.
Q. She is still not taking any action and getting even closer. What will be your action now?
A. As per Rule 17, since it is apparent to me that the other vessel is not taking any action, I will take the action by sounding one short blast and alter course to starboard to take a round turn and pass astern of her. As per Rule 17 I will not alter course to port for a vessel on my own port side.
SITUATION 04
Q. You are the OOW of a power-driven vessel. You see this light. What do the light indicate to you?
A. A sailing vessel underway, port side on, not showing optional sailing lights.
Q. You see this vessel 30° on the starboard bow. What action will you take?
A. I will take a series of compass bearings of the approaching vessel and, if the compass bearing does not change appreciably, then the risk of collision exists.
Q. The bearing is constant and range decreasing. What action will you take now?
A. As per Rule 18 it is my responsibility to keep clear of a sailing vessel so my vessel is the give-way vessel and the sailing vessel is to stand on. I will sound one short blast and make a broad alteration of the course to starboard and pass well clear of the other vessel.
SITUATION 05
