While talking about the history of the Chesapeake & Delaware Canal during the Civil War at a meeting of the Fort Delaware Society last week, we discussed the website, www.marinetraffic.com. This open source initiative provides free, real-time information about ship movements so visitors are able to view marine traffic on the Delaware and Chesapeake bays and the Canal. It is also provides details on the vessels. Many guests at the program were interested in this virtual information repository, so I am posting the link here.
