If a supertanker comes up behind me while transiting the C&D. Will it try to pass me or is passing not allowed? Do I yield towards the center or the side if not?
Passing is permitted.
They may have the right of way if they must maintain steerage speed and that is faster than you are going... not sure...
I recently transited on a Saturday... not a commercial vessel to be seen. No shortage of jet skis, cigarette boats, and cruisers. Maybe the professionals avoid the place on a weekend?
FWIW, it's much more beautiful and scenic than I would have imagined.
