Si el abordaje no es inminente, ¿cómo debe actuar?A power-driven vessel sees a sailing vessel at 115º relative bearing to starboard approaching with risk of collision. If collision is not imminent, how should she act?

Why the others are not

  • b) She is overtaking us.
  • c) Speed too must be kept.
  • d) No action due.

How to work it out in the exam

  1. Over 22.5º abaft the beam: overtaking.
