The charted depth alongside the south face of Mystic Pier, Charlestown, MA, is 35 feet. Your maximum draft is 38 feet. You wish to have 2 feet under the bottom, on a rising tide, when you go alongside to discharge a heavy lift. What is the earliest time after 0900 EST (ZD +5), on 2 February 1983, that you can dock?

Question

Accepted Answer

Option D: 1137. Draft (38') minus charted depth (35') plus 2 feet clearance requires a rising tide height of 5 feet. Consult Mystic Pier tide tables for 2 February 1983, interpolating the rising curve after 0900 EST to find when the water level reaches 5 feet.
