(a)
-
(i) Where one of two vessels is to keep out of
the way the other shall keep her course and speed.
-
(ii) The latter vessel may however take action
to avoid collision by her manoeuvre alone, as soon as it becomes apparent
to her that the vessel required to keep out of the way is not taking
appropriate action in compliance with these Rules.
(b) When, from any cause, the vessel required
to keep her course and speed finds herself so close that collision
cannot be avoided by the action of the give-way vessel alone, she
shall take such action as will best aid to avoid collision.
(c) A power-driven vessel which takes action in
a crossing situation in accordance with subparagraph (a)(ii) of this
Rule to avoid collision with another power-driven vessel shall, if
the circumstances of the case admit, not alter course to port for
a vessel on her own port side.
(d) This Rule does not relieve the give-way vessel
of her obligation to keep out of the way.
