Vessels may be so anchored as to swing into the main ship channels only if they are so placed with reference to the customary winds, tides, and currents of the harbor, as to swing only during slack water, and that during this period there shall remain in the waters adjacent to the channel an area of sufficient depth as to permit the safe passage of loaded vessels.(3) No vessel may anchor within the designated anchorages for more than 72 hours without the prior approval of the Captain of the Port.(4) No vessel may anchor unless it maintains a bridge watch, guards and answers Channel 16 FM, and maintains an accurate position plot.(5) If any anchored vessel is so close to another that a collision is probable, each vessel must communicate with the other vessel and the Captain of the Port on Channel 16 FM and shall act to eliminate the close proximity situation.(6) No vessel may anchor unless it maintains the capability to get underway within 4 hours.(7) No vessel may anchor in a "dead ship" status (propulsion or control unavailable for normal operations) without the prior approval of the Captain of the Port.(8) Dragging of anchors in or across main ship channels and cable areas is prohibited.(9) Vessels which, through force of great emergency, are anchored contrary to the foregoing regulations in this section shall be shifted to new berths in accordance with such regulations at the earliest opportunity.(10) A vessel, upon notification from the Captain of the Port to shift its position in anchorage grounds must get underway at once or signal for a tug, and must change position as directed with reasonable promptness.(11) No vessel may conduct lightering operations in an anchorage without permission from the Captain of the Port.(12) When the use of an anchorage is required by naval vessels, the vessels anchored therein shall move when the Captain of the Port directs them.(13) Nothing in this section shall be construed as relieving the owner or person in charge of any vessel from the penalties of law for obstructing navigation, or for obstructing or interfering with range lights, or for not complying with the navigation laws in regard to lights, fog signals, etc.CGD7 83-15, 49 FR 26587, June 28, 1984
