Module 5 - COLREGs

Stand-On and Give-Way Obligations

Active recall

Section 7 of 9

Explain the main idea from stand-On and Give-Way Obligations in your own words.

Rule 16 (Give-way vessel): Must take early and substantial action to keep well clear.

Rule 17 (Stand-on vessel): initially keeps course and speed, may act when it becomes apparent that the give-way vessel is not taking appropriate action, and must take the action that best avoids collision when collision cannot be avoided by the give-way vessel alone. In a crossing situation between two power-driven vessels, a stand-on vessel acting under Rule 17(a)(ii) should, if circumstances allow, avoid altering to port for a vessel on her own port side.

Key points

  • Give-way vessel: act early and substantially
  • Stand-on vessel: maintain course and speed initially
  • Stand-on vessel MUST act if give-way vessel doesn't
  • Stand-on: avoid altering to port for vessel on port side
