Course Outline

In open waters, you may be sharing the channels with commercial shipping vessels.

  • Avoid commercial shipping traffic lanes by as wide of a margin as possible.
  • If you must cross a shipping lane, cross as quickly as possible and at 90 degrees to the prevailing traffic or as practical.
  • To identify marked shipping channels, see the information about the U.S. Aids to Navigation System (ATONS) earlier in this unit.
