Subpart D--Professional Requirements for National Deck Officer
Endorsements

Sec.  11.401  Ocean and near-coastal national officer endorsements.

    (a) Subject to the provisions of Sec. Sec.  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 Sec. Sec.  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.

Sec.  11.402  Tonnage requirements for national ocean or near-coastal
endorsements for vessels of 1,600 GRT or more.

    (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.

Sec.  11.403  Structure of national deck officer endorsements.

    Figure 11.403 illustrates the national deck officer endorsement
structure, including crossover points. The section numbers on the
diagram refer to the specific requirements applicable.

endorsement is limited to the maximum tonnage on which at least 25
percent of the required service 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 1,000
GRT, using the next higher figure when an intermediate tonnage is

limitation in that capacity equal to 150 percent of the tonnage of that
vessel.

GRT results in raising the limitation to 5,000 GRT.

    (iv) Six months of service as mate on vessels more than 1,600 GRT
results in raising the limitation for master to the tonnage on which at
least 50 percent of the service was obtained.
    (v) Two years of service as a deckhand on a vessel while holding a
license or MMC endorsement as master results in a limitation on the MMC
equal to 150 percent of the tonnage of that vessel up to 5,000 GRT.
    (vi) One year of service as deckhand on a vessel while holding a
license or MMC endorsement as master results in a limitation on the MMC
equal to the tonnage of that vessel.
    (d) An applicant for an endorsement as mate of uninspected fishing
industry vessels must have 3 years of total service on ocean or near-
coastal routes. Service on Great Lakes or inland waters may substitute

year of the required service must have been on vessels of 50 GRT or
more.
    (2) To qualify for an endorsement of less than 1,600 GRT, at least

more.
    (3) To qualify for an endorsement of more than 1,600 GRT, but not

required service was obtained will be used to compute the tonnage. The
endorsement is limited to the maximum tonnage on which at least 25
percent of the required service 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 1,000
GRT, using the next higher figure when an intermediate tonnage is
calculated.
    (4) The tonnage limitation on this endorsement may be raised using
one of the following methods, but cannot exceed 5,000 GRT. Limitations
are in multiples of 1,000 GRT, using the next higher figure when an
intermediate tonnage is calculated.
    (i) Three months of service as mate on a vessel results in a
limitation in that capacity equal to the tonnage of that vessel rounded
up to the next multiple of 1,000 GRT.
    (ii) Six months of service as mate on a vessel results in a
limitation in that capacity equal to 150 percent of the tonnage of that
vessel.
    (iii) Six months of service as mate on vessels more than 1,600 GRT
results in raising the limitation to 5,000 GRT.
    (iv) One year of service as deckhand on vessels more than 1,600 GRT
while holding a license or MMC endorsement as mate, results in raising
the limitation on the MMC to 5,000 GRT;
    (v) Two years of service as a deckhand on a vessel while holding a
license or MMC endorsed as mate results in a limitation on the MMC
equal to 150 percent of the tonnage of that vessel up to 5,000 GRT.
    (vi) One year of service as deckhand on a vessel while holding a
license or MMC endorsement as mate results in a limitation on the MMC
equal to the tonnage of that vessel.
