(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 its engines ready for immediate maneuver.
(D) A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing or risk of collision exists. If so, it shall take avoiding action in ample time, provided that when such action consists of an alteration of course, so far as possible the following shall be avoided: an alteration of course to port for a vessel forward of the beam, other than for a vessel being overtaken and an alteration of course toward a vessel abeam or abaft the beam.
(E) Except where it has been determined that a risk of collision does not exist, every vessel which hears apparently forward of its beam the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of its beam, shall reduce its speed to the minimum at which it can be kept on course. It shall if necessary take all its way off and, in any event, navigate with extreme caution until danger of collision is over.
No person shall operate or permit to be operated, any vessel on the waters in this state, in violation of this rule.
