The International Collision Regulations, in Part B -- Steering and
Sailing Rules, Section II -- Conduct of Vessels in Sight of One Another, require:

"Notwithstanding anything contained in the Rules of Part B, Sections I
and II, any vessel overtaking any other vessel shall keep out of the way
of the vessel being overtaken". [This particular wording is from the
Canadian regulations but it is likely identical in meaning to all other
national implementations of the international rules.]

That provision supersedes the precedence of sail over power, starboard
over port, leeward over windward and even of a vessel restricted in her
ability to manoeuvre over everything else (though going slowly in front
of one of those while it overtakes is NOT recommended). In short, when
approaching any vessel from more than two points abaft her beam, you are
required to keep clear.

There is no requirement for the overtaking vessel to opt for one side or
the other of the vessel being overtaken.
