Examination
DECK EXAMINATION GUIDE: ESS 5-1. At this link, you will find two Deck Examination Guides. If you submitted your application after March 24, 2019, you will be taking the exams described in the new Examination Guide. The old guide’s examinations were 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.
