(a)Detroit River. The following traffic rules apply in the Detroit River:
(1) The West Outer Channel is restricted to downbound vessels.
(2) The Livingston Channel, west of Bois Blanc Island, is restricted to downbound vessels.
The Amherstburg Channel, in Canadian waters east of Bois Blanc Island, is normally restricted to upbound vessels. No vessel may proceed downbound in the Amherstburg Channel without authorization from the Regional Director General.
(c)St. Clair River. The following traffic rules apply in the St. Clair River:
(2) Between Lake Huron Cut Lighted Buoy 1 and Port Huron Traffic Lighted Buoy there is a zone of alternating one way traffic. Masters shall coordinate their movements in accordance with the following rules;
(i) Vessels shall not overtake.
(ii) Vessels shall not come about.
(iii) Vessels shall not meet.
(iv) Downbound vessels which have passed Lake Huron Cut Lighted Buoy 7 have the right of way over upbound vessels which have not reached the Port Huron Traffic Lighted Buoy. Upbound vessels awaiting transit of downbound vessels will maintain position south of the Port Huron Traffic Lighted Buoy.
(d) In the waters described in § 162.130(a), the District Commander or Captain of the Port may establish temporary traffic rules for reasons which include but are not limited to: channel obstructions, winter navigation, unusual weather conditions, or unusual water levels.
(e) The requirements of this section do not apply to public vessels of the U.S. or Canada engaged in icebreaking or servicing aids to navigation or to vessels engaged in river and harbor improvement work.
(f) The prohibitions in this section on overtaking in certain areas do not apply to vessels operating in the nondisplacement mode. In this section, “nondisplacement mode” means a mode of operation in which the vessel is supported by hydrodynamic forces, rather than displacement of its weight in the water, to an extent such that the wake which would otherwise be generated by the vessel is significantly reduced.
