Heading South in Lake Huron

We passed thru Mackinac today. We are southbound under motor in Lake Huron near Thunder Bay. The wind is very light and directly in our face with light rain and thunderstorms in the area. We will pass near the site where the our first Reboot, a Catalina 30, was hit by a commercial ship many years ago when my children were very young. We have a parade of commercial vessels coming north and passing us. About an hour ago a sailboat under spinnaker came ghosting by heading North.
