The give-way vessels has the burden of
taking actions early and pronounced accompanied
by appropriate communications,
whistle signals or radio or both. Starboard
turns away from meeting vessels are preferred.
In crossing situations turns to pass
astern of the stand-on vessel are preferred.
Slowing will also provide the stand-on vessel
a comfortable change in the relative bearing
indicating safe passage.
Action by Stand-on Vessel
(Rule 17)
(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 maneuver 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 giveway
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 Rule 17(a)(ii) 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.
The stand-on vessel is to hold course
and speed, however when circumstances
show the give-way vessel is not complying
with the Rules, action by the stand-on
vessel to avoid action is required to avoid
collision. Rule 2 provides this authority to
avoid immediate danger.
Responsibilities Between Vessels
(Rule 18)
Except where Rules 9, 10, and 13 otherwise
require:
(a) A power-driven vessel underway shall
keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to
maneuver;
(iii) a vessel engaged in fishing;
(iv) a sailing vessel.
(b) A sailing vessel underway shall keep out
of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to
maneuver; and
(iii) a vessel engaged in fishing.
(c) A vessel engaged in fishing when underway
shall, so far as possible, keep out of
the way of:
(i) a vessel not under command; and
(ii) a vessel restricted in her ability to
maneuver.
This rule clarifies the situations wherein
a powerboat and sail boat are in the overtaking,
crossing or meeting situations, and
specifies when sailboats shall keep out of
the way.
Conduct of Vessels in
Restricted Visibility
Conduct of Vessels in Restricted
Visibility (Rule 19)
(a) This Rule applies to vessels not in sight
of one another when navigating in or
near an area of restricted visibility.
(b) Every vessel shall proceed at a safe speed
adapted to the prevailing circumstances
and conditions of restricted visibility.
A power-driven vessel shall have her
engines ready for immediate maneuver.
