§ 281 Vessel Collision Avoidance Rules

When two boats are moving toward each other and could hit, each must turn right (give right rudder) so they pass each other on the left side.

Key Takeaways

  • •Both vessels must give right rudder (turn to starboard).
  • •They must pass each other on the port (left) side.
  • •They can only break the rule if it’s needed to avoid immediate danger.

Example

A steam-powered ferry is heading north while a sailing yacht is heading south on the same channel. They see each other and could collide if they keep going straight.

Both the ferry and the yacht turn to their right so each passes on the left side of the other, avoiding a crash.

§ 281 Vessel Collision Avoidance Rules

Whenever any vessel, whether a steam vessel or sailing vessel, proceeding in one direction, meets another vessel, whether a steam vessel or sailing vessel, proceeding in the opposite direction, so that if both were to continue their respective courses they would pass so near as to involve the risk of a collision, each shall give right rudder, so as to pass on the port side of each other. This rule applies to all steam vessels and all sailing vessels whether on the port or starboard tack, and whether close-hauled or not, except where the circumstances of the case are such as to render a departure from the rule necessary in order to avoid immediate danger. It is subject to a due regard to the dangers of navigation, and, as regards sailing vessels on the starboard tack close-hauled, it is subject also to the keeping of such sailing vessels under command. (Enacted by Stats. 1937, Ch. 368.)
