19. You are bound for Baltimore via Cape Henry on a 15 knot ship. If the flood at Chesapeake Bay entrance begins at 1800 EST (ZD +5), at what time would you depart from the Chesapeake Bay entrance to have the most favorable current?

To maximize the favorable flood current into the Chesapeake Bay for a voyage to Baltimore, departure should occur approximately 2-3 hours after the flood's commencement, typically around 2030 hours, when the current reaches its peak strength.
