Re: Recreational Sailboat vs. Tugboat with Barge: Who Has the Right of Way? - See mor
I would also add that recreational boaters need to be aware of and stay clear of any local Traffic Separation Schemes. Since San Francisco has a large one, it probably didn't matter much to the article. Commercial vessels even if they can navigate outside a scheme can be prohibited from exiting, much like if they were in a narrow channel surrounded by shallow water.
They are still the give way vessel, however a vessel transiting across a TSS always gives way.
