How far ahead of you did the ferry pass? Maybe her appreciation of
the situation was different from your. Her ARPA may have indicated
a safe CPA astern (one that the ferry was comfortable with) while
you were eyeballing it.

The ferry is an older and minimally equipped boat. Judging by how
close I was amidships at the pass there absolutely would have been
contact if I had stood on.
