280. You are to sail from Elizabethport, N.J., on 22 May 1983, with a maximum draft of 28 feet. You will pass over an obstruction in the channel near Sandy Hook that has a depth of 26.5 feet. The steaming time from Elizabethport to the obstruction is 1h 40m. What is the earliest time (ZD + 4) you can sail on the afternoon of 22 May and pass over the obstruction with 2 feet of clearance?
A draft of 28 feet requires a minimum water depth of 30 feet to maintain 2 feet of clearance over an obstruction with a charted depth of 26.5 feet. The earliest departure time to achieve this is 1342, calculated by determining the time the tide reaches the necessary height and subtracting the steaming time.
