This is a PowerPoint presentation I have given several times covering Sound Signals for the Rules of the Road in Puget Sound.  Puget Sound does have some Local Customs with sound signals and the Ferries.   This is a subset of rules but it does cover  sound signals most likely to be seen by small boaters in the Puget Sound Area. (Approximately  12 minutes long)
