USCG Master 100 study guide

The USCG Master 100 Gross Register Tons credential - commonly called Master 100 Ton or Master 100 GRT - is a merchant mariner officer endorsement that qualifies the holder to serve as master of inspected steam or motor vessels of not more than 100 gross register tons, subject to the limits and conditions printed on the credential itself. Candidates are typically owner-operators, charter and small passenger vessel captains, tug and workboat operators, and deckhands moving up from an Operator of Uninspected Passenger Vessel or mate-level endorsement. The examination is a multiple-choice test covering four knowledge areas: Rules of the Road, Navigation General, Deck General, and Deck Safety. Rules of the Road tests inland and international steering-and-sailing rules, lights, shapes, and sound signals; Navigation General covers piloting, chart work, tides and currents, and terrestrial navigation; Deck General covers seamanship, vessel handling, stability, and mariner regulations; Deck Safety covers lifesaving equipment, firefighting, damage control, and emergency procedures.
