17. Passing Rules Explained Simply (COLREGs Made Practical)

Why Passing Rules Matter

Most boating collisions happen because operators:

  • Don’t understand right-of-way
  • React too late
  • Don’t communicate intentions

Reference:

USCG Navigation Rules

The Basic Passing Situations

Crossing Situation

  • Vessel on your starboard (right) side has right-of-way
  • You must give way early

Head-On Situation

  • Both vessels turn to starboard (like driving a car)

Overtaking

  • The vessel overtaking must keep clear

Signal Your Intentions EARLY

Do not wait until the last second.

Use:

  • Course adjustments early and clearly
  • Sound signals (short blasts)
  • VHF radio when appropriate

Early communication prevents confusion.

What Goes Wrong

Most issues happen when:

  • Operators hesitate
  • Both vessels assume the other will move
  • No clear signal is given
