(a) Subject to the provisions of §§ 11.464(e) and 11.465(b) of this subpart, any license or MMC endorsement for service as master or mate on ocean waters qualifies the mariner to serve in the same grade on any waters, except towing vessels upon western rivers subject to the limitations of the endorsement.

(b) Subject to the provisions of §§ 11.464(e) and 11.465(b) of this subpart, any license or MMC endorsement issued for service as master or mate on near-coastal waters qualifies the mariner to serve in the same grade on Great Lakes and inland waters, except towing vessels upon western rivers subject to the limitations of the endorsement.

(c) Near-coastal endorsements for unlimited tonnage require the same number of years of service as the ocean-unlimited endorsements. The primary differences in these endorsements are the nature of the service and the scope of the required training, examination, and assessment.

(d) A master or mate on vessels of 200 GRT or more, and a master or mate on vessels under 200 GRT, may be endorsed for sail or auxiliary sail as appropriate. The applicant must present the equivalent total service required for conventional officer endorsements, including at least 1 year of deck experience on that specific type of vessel. For example, for an officer endorsement as master of vessels of less than 1,600 GRT endorsed for auxiliary sail, the applicant must meet the total experience requirements for the conventional officer endorsement, including time as mate, and the proper tonnage experience, including at least 1 year of deck service, on appropriately sized auxiliary sail vessels. For an endorsement to serve on vessels of less than 200 GRT, see the individual endorsement requirements.

(e) Service toward an oceans, near-coastal or STCW endorsement will be credited as follows:

(1) Service on the Great Lakes will be credited on a day-for-day basis.

(2) Service on inland waters, other than Great Lakes, that are navigable waters of the United States, may be substituted for up to 50 percent of the total required service.

(3) Service on vessels to which STCW applies, whether inland or coastwise, will be credited on a day-for-day basis.

(a) To qualify for a national ocean or near-coastal endorsement for service on vessels of unlimited tonnage—

(1) All the required experience must be obtained on vessels of 100 GRT or more; and

(2) At least one-half of the required experience must be obtained on vessels of 1,600 GRT or more.

(b) If an applicant for a national endorsement as master or mate of unlimited tonnage does not have the service on vessels of 1,600 GRT or more as required by paragraph (a)(2) of this section, a tonnage limitation will be placed on the MMC based on the applicant's qualifying experience. The endorsement will be limited to the maximum tonnage on which at least 25 percent of the required experience was obtained, or 150 percent of the maximum tonnage on which at least 50 percent of the service was obtained, whichever is higher. However, the minimum tonnage limitation calculated according to this paragraph will be 2,000 GRT. Limitations are in multiples of 1,000 GRT using the next higher figure when an intermediate tonnage is calculated. When the calculated limitation equals or exceeds 10,000 GRT, the applicant is issued an unlimited tonnage endorsement.

(c) Tonnage limitations imposed under paragraph (b) of this section may be raised or removed in one of the following manners:

(1) When the applicant provides evidence of 6 months of service on vessels of 1,600 GRT or more in the highest grade endorsed, all tonnage limitations will be removed.

(2) When the applicant provides evidence of 6 months of service on vessels of 1,600 GRT or more in any capacity as an officer other than the highest grade for which he or she is endorsed, all tonnage limitations for the grade in which the service is performed will be removed and the next higher grade endorsement will be raised to the tonnage of the vessel on which the majority of the service was performed. The total cumulative service before and after issuance of the limited license or MMC officer endorsement may be considered in removing all tonnage limitations.

(3) When the applicant has 12 months of service as able seaman on vessels of 1,600 GRT or more while holding a license or endorsement as third mate, all tonnage limitations on the third mate's license or MMC officer endorsement will be removed.

(d) No applicant holding any national endorsement as master or mate of vessels of less than 1,600 GRT, less than 500 GRT, or less than 25-200 GRT may use the provisions of paragraph (c) of this section to increase the tonnages of his or her license or endorsement.

Service on inland waters may substitute for up to 50 percent of the required service. At least one-half of the required experience must be served as chief mate.

In no case will the limitation exceed 10,000 GRT/GT for OSVs unless the applicant meets the full requirements for an unlimited tonnage endorsement.

(d) A person holding an endorsement as master (OSV) may qualify for an STCW endorsement, according to §§ 11.305 and 11.311 of this part.

The endorsement will be limited to the maximum tonnage on which at least 25 percent of the required experience was obtained, or 150 percent of the maximum tonnage on which at least 50 percent of the service was obtained, whichever is higher. However, the minimum tonnage limitation calculated according to this paragraph will be 2,000 GRT. Limitations are in multiples of 1,000 GRT using the next higher figure when an intermediate tonnage is calculated. In no case will the limitation exceed 10,000 GRT/GT for OSVs unless the applicant meets the full requirements for an unlimited tonnage endorsement.
