Peter:

Transiting the Detroit and St. Clair Rivers is relatively easy. Make sure you have the "book chart" (I don''t have the number off hand) that covers from the lower Detroit River to Port Huron. The currents in both rivers run about 1 1/2 to 2 knots except for the final stretch under the Blue Water Bridge at Port Huron where the constriction accelerates it to about 4 knots for about a 1/2 mile until you pop thru (hug the Canadian shore to reduce this effect). As far as commercial traffic, it is pretty constant, but there is usually plenty of water outside the marked channel, so you just pop outside the buoys when encountering a freighter and you''re all set. They are speed restricted in both rivers, so they are not throwing tremendous wakes. Hope you make the trip.
