The only TSS that I am aware of is at the entrance to the Delaware Bay (see chart 12214). We are 100 miles upriver from that. There is a channel in my part of the river, but it is not part of a TSS.
There is no way that am the stand on vessel if one of those tankers is bearing down on me in the channel. Anyone who travels this river would realize how absurd that suggestion is.
If you reread the COLREG that I posted, it clearly says that it applies to areas where there is NOT a TSS:
Restricted in maneuvering has a specific meaning as per 3(g):
The term “vessel restricted in her ability to manoeuvre” means a vessel which from the nature of her work is restricted in her ability to manoeuvre as required by these Rules and is therefore unable to keep out of the way of another vessel. The term “vessels restricted in their ability to manoeuvre” shall include but not be limited to:
a vessel engaged in laying, servicing or picking up a navigation mark, submarine cable or pipeline;
a vessel engaged in dredging, surveying or underwater operations;
a vessel engaged in replenishment or transferring persons, provisions or cargo while underway;
a vessel engaged in the launching or recovery of aircraft;
a vessel engaged in mine clearance operations;
a vessel engaged in a towing operation such as severely restricts the towing vessel and her tow in their ability to deviate from their course.
As such, if you are under sail, you are stand on. Even if under power, you still are stand on in the case of being overtaken.
