Collision Avoidance, keep out of the way
I am going to take a regular series of compass bearings of the approaching vessel and if the compass bearings remain constant then rosk of collision is deemed to exist.
(Point at it) - This is the stand on vessel
I am the ‘keep out of the way’ vessel and shall sound one short blast on the ships whistle of about 1 seconds duration and make a bold alteration of course to starboard (or port) of about 40 to 60 degrees. I will monitor the situation until finally past and clear and then return to my original course.
Rule 17 Action by stand-on vessel
I am going to take a regular series of compass bearings of the approaching vessel and if the compass bearings remain constant, then risk of collision is deemed to exist.
I am the Stand on Vessel. I shall maintain my course and speed.
I may however take action by my manoeuvre alone, as soon as it become apparent that the other vessel is not taking appropriate action in compliance with these Rules.
If so, I shall sound five short rapid blasts, inform the Master, engage hand steering. If there is no response, then sound one short blast and go to starboard. (Can’t go to Port at the May stage for a PDV)
If the vessel required to keep her course and speed finds herself so close that action by give way vessel alone cannot avoid collision.
I shall take such action as will best avoid collision.
(Can go to Port or Starboard)
I would sound five short blasts and take any action.
Collision avoidance + shall not impede (inside a
Narrow channel or TSS)
I am going to take a regular series of compass bearings of the approaching vessel and if the compass bearing remains constant or does not appreciably change, then risk of collision is deemed to exist:
This is Rule 18/15; I am the give-way vessel.
However, under rule 10 this vessel is required to not impede my safe passage. I shall sound 5 short rapid blasts to remind her of her obligation to not impede.
If there is no response then the normal Steering and Sailing Rules apply when there is risk of collision and will act accordingly.
You sight a CBD
I am going to take regular series of compass bearing of the approaching vessel and if the compass bearings remain constant or does not appreciably change then risk of collision is deemed to exist.
I am the “shall not impede” vessel. I shall take early action to allow sufficient sea room for the safe passage of the vessel not to be impeded.
I will sound 1 short blast and alter to Starboard to parallel the other vessel’s course.
(I will not alter to port for CBD on my own port side if risk of collision exists).
