At least where the international rules are applicable, the priority of
sail over typical power boats (and of vessels not under command,
restricted in their ability to manoeuvre, constrained by their draft,
fishing etc. over both) is in the rules for vessels within sight of one
another. So are the priorities of starboard over port and leeward over
windward. They do not apply to vessels in fog so dense that one cannot
be seen from the other.
