11.422—Tonnage limitations and qualifying requirements for endorsements as master or mate of vessels of not more than 200 gross tons.

(a) Except as noted in paragraph (e), all endorsements issued for master or mate of vessels of not more than 200 gross tons are issued in 50 gross ton increments based on the applicant's qualifying experience. The endorsement is 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. Limitations are in multiples of 50 gross tons using the next higher figure when an intermediate tonnage is calculated.
(b) The tonnage limitation on these endorsements may be raised upon completion of:
(1) At least 45 days of additional service on deck on a vessel of a higher tonnage for a tonnage increase on a mate's endorsement; or,
(2) At least 90 days of additional service on deck on a vessel of a higher tonnage for a tonnage increase on a master's endorsement; or,
(3) Additional service, which, when combined with all previously accumulated service, will qualify the applicant for a higher tonnage officer endorsement under the basic formula; or,
(4) Six months additional service in the deck department on vessels within the highest tonnage increment on the officer's license or MMC endorsement. In this case, the tonnage limitation may be raised one increment.
(c) When the service is obtained on vessels upon which no personnel need an officer endorsement or license, the OCMI must be satisfied that the nature of this qualifying service (i.e., size of vessel, route, equipment, etc.) is a reasonable equivalent to the duties performed on vessels which are required to engage individuals with officer endorsements.
(d) Service gained in the engine room on vessels of not more than 200 gross tons may be creditable for up to 25 percent of the deck service requirements for mate.
(e) When the qualifying service is obtained upon vessels of five gross tons or less, the officer endorsement will be limited to vessels of not more than 25 gross tons.
