USCG Application Information
Merchant Mariner Credentials (MMC) are issued by the US Coast Guard and
authorize the authority to work on, operate, or stand a watch on
commercial vessels. This include all forms of vessels from small fishing
guide boats to the largest Merchant Ships. Merchant Mariner Credentials
(MMC) are issued as endorsements.
MMC Officer's Endorsements includes OUPV, Master and Mate. These
endorsements are commonly referred to as licenses and issue the
authority to be in charge of the vessel or to be in charge of a navigational
watch on the vessel.
MMC Rating Endorsements includes ordinary seaman and able seaman.
These endorsements are commonly referred to as an MMD (Merchant
Marine Document) or a "Zcard" and issue the authority to work as a
deckhand in different capacities on commercial vessels.
MMC STCW International Endorsements are required for ships greater
than 200 tons on international voyages.

Three letters of character reference are required for an application for
an original MMC officers endorsement. You do not need to provide
character references for any rating endorsement or for an upgrade to
an existing license.
Sea Service Experience
Most MMC Endorsements require the mariner to document sea service
experience. This represents your experiences involving boats over the
course of you lifetime and can include experience with most any type of
vessel on any waters, but you must be able to document the experience.
Documenting Sea Service Experience
The easiest way to document sea service experience on small vessels
is to use the small boat sea service form 719S provided by the
USCG. Complete one form for every vessel you are claiming
experience on and have the vessel owner or the operator sign the
form documenting your experience. If you were the owner than you
will need to provide proof of ownership to document your experience.
Inland verses Ocean sea service
The boundary line, sometime called the demarcation line, divides
inland and ocean sea service. This is a line drawn at the most
seaward points of land at the entrance to rivers, bays, harbors and
sounds. For southeastern Alaska it is a line drawn between the most
seaward points of the inlands and for the Straights of Juanda Fuca it
is a line drawn directly north from Point Angeles to the US-Canadian
border.
- Any day served aboard a vessel operating on waters shoreward
of the boundary line is an inland sea day.
- Any day served aboard a vessel operating on waters seaward
of the boundary line is an ocean sea day.
Sea Service Experience Definitions
Sea service experience is measured in eight-hour calendar days.
1 Sea Day
Any day that you are on a boat, had a position of authority
such as deckhand, helmsman or lookout, and were away from
the dock for more than 4-hours counts as one eight-hour day.
One month of sea service is equal to 30 days.
One year of sea service is equal to 12 months or 360 days.
Recent sea service is required to qualify for any MMC officers
endorsement or to upgrade any officer endorsement. It is not
required for AB ratings. Recent sea service means 90 days of
sea service experience within the past three years.
