The Boundary Line

What is this mysterious Boundary Line that the USCG refers to on its sea service forms?

Since the late 1980s, the USCG has used this line to delineate between "inland" vs. "near coastal" waters for licensing purposes. And the same line is used to determine where STCW is applicable. STCW is applicable seaward of the Boundary Line, and STCW is not applicable shoreward of the Boundary Line. You won't find the Boundary Line on any navigational chart, because the Boundary Line is not used for navigational purposes. The Boundary Line is NOT to be confused with any of the following:

  • COLREGS Demarcation Line (used only to determine where Inland vs. International rules of the road apply)
  • 3 mile limit (delineates the seaward territorial border of the U.S.)
  • 12 mile limit (delineates the seaward border used to enforce U.S. Customs and other laws)
  • Territorial Sea Baseline (across the mouth of wide rivers and bays to measure where the 3 and 12 mile limits are measured from)

To find where the Boundary Line is for the contiguous U.S., use this link to 46 CFR Part 7

Gulf of Mexico exception: 46 CFR Part 7 delineates that the Boundary Line in the Gulf of Mexico is along the 12-mile line which marks the seaward limits of the territorial sea. However, for the purpose of crediting sea service in the Gulf of Mexico for the issuance of licenses, the USCG has published NMC Policy Letter No. 1-2000 dated 3/15/00 that allows service between the Territorial Sea defined at 33 CFR 2.05-10 and the Boundary Line defined at 46 CFR Part 7 to be considered near coastal waters.
