Port Townsend Wooden Boat Festival 2026

There are numerous historic ship and plane wrecks on the deep seafloor in the Pacific that resulted from accidents, wars, and purposeful disposals.  Locating and surveying these wrecks benefits the understanding of our cultural heritage and provides reasons to resurrect their history and stories of heroism and tragedy.  I and others have found wrecks thousands of feet below the surface by beginning with a review of available information on their sinking.   This is followed by the use of various types of sonar and software to identify potential targets to investigate.  Describing these techniques is the topic of this presentation.
