Any action taken to avoid collision shall, if the circumstances of the case admit, be positive, made in ample time and with due regard to the observance of good seamanship.

• If safe to do so, (if the circumstances of the case admit) any alteration of course or speed to avoid collision will be substantial enough for others to see.
• Smaller adjustments afterward should be avoided to avoid confusion.
• Altering course may be the most effective solution against collision given:
  • Enough room to maneuver
  • Is made in time
  • Is substantial
  • Does not result in another collision risk
• Collision avoidance equals passing at a safe distance with the situation carefully monitored until the vessels are safely past and clear.
• Slow or reverse speed to give more time to assess the situation or avoid a collision.
• A vessel not required to get in the way of another shall stay clear to allow for safe passage.
• Even a vessel that everyone else should be out of the way for is still bound to take appropriate action to avoid a collision.
