The Master Great Lakes & Inland waters allows the holder to serve as Master or Mate on vessels of any tonnage on the Great Lakes & Inland waters. The Master Inland AGT permits the holder to serve as Master on vessels of any tonnage on Inland waters (not including the Great Lakes). After 30 days of training and observation on towing vessels and the completion of a TOAR (Towing Officer’s Assessment Record), the mariner may serve as a Master Towing Inland (or Great Lakes, if appropriate).
RECENCY: 90 days in the past 3 years on vessels of appropriate tonnage
DECK EXAMINATION GUIDE: There are currently two 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 (page 82). The old examinations are significantly less difficult in most cases than the New Examinations (page 23).
The term “qualifying service” needs some clarification. The qualifying service required for a raise-in-grade of a credential includes time served under the authority of a previous credential. For example, if a mariner received his or her Mate Inland AGT credential after March 24, 2014, all of the qualifying service, the time served while holding a credential, would have been acquired after March 24, 2014 and he or she would have no choice but to take the new examinations. On the other hand, a mariner wishing to get a Mate Inland AGT based on service that began before March 24, 2014, has the option of testing under the old or the new examination scheme.
