Examination
DECK EXAMINATION GUIDE: ESS 5-1. At this link, you will find two Deck Examination Guides. If your qualifying service for the license began before March 24, 2014, you may opt to be examined under the procedures of the old Deck Examination Guide. The old guide’s examinations are significantly less difficult in most cases than the new guide’s. Note: If a mariner holds an Apprentice Mate Towing, he or she can by service alone raise-in-grade to Mate Towing and Master Towing on the same route. No examination required. If a mariner holds a Master or Mate Towing Inland and wishes to extend its scope to Near Coastal and Ocean, an examination on the new route will be required.
