Twisted, my experience mirrors yours with ferries. Even with them however, if I can easily do so, I will alter my course long before there is ever a question as to a possible conflict. This allows the ferry to continue on their route unimpeded. The key in my own mind is to make that change very early and very clear. Most of the time, I am in the South Sound and not up around Seattle where there is a lot more traffic to contend with. In the Seattle area, there can be several ferries that could have a conflict with you at any given time as well as working around the traffic separation lanes. Being predictable and maintaining course as the stand on vessel is more important there.
...predictable and/or communicate. Random helmsmanship is of no use to anyone.
