Study Notes
Vessel Communication and Signals
- A vessel can use sound or light signals not mistaken for authorized signals, except those listed under Annex IV of the Collision Regulations.
- A searchlight beam can be used to attract attention, while a burning barrel and "Mayday" call are distress signals.
Anchor Signals
- A 200-meter vessel at anchor should display a 225-degree white light in the forepart and a 135-degree white light in the after part, along with possible working lights.
Fog Signals
- Only designated vessels in restricted visibility can sound specific fog signals; for instance, one prolonged and two short blasts.
- Vessels under tow and fishing vessels may not sound one prolonged and two short blasts.
Overtaking and Crossing Situations
- When overtaking another vessel without changing course, no whistle signals are required.
- In crossing situations where a vessel sounds a short blast, the appropriate response is to hold course and speed, or reply accordingly.
Vessels' Maneuverability
- A vessel constrained by its draft, fishing with trawls or engaged in mineclearing is classified as restricted in ability to maneuver.
- "Under command" vessels may act differently from those that are "not under command," which cannot maneuver effectively.
Navigation Responsibilities
- Changing course to avoid collisions should be a large or small alteration supplemented by speed adjustments.
- The presence of a pilot does not absolve the master and officers of the vessel from navigation responsibilities.
Lighting and Signaling Requirements
- A towing vessel pushing a barge must exhibit the lights of a power-driven vessel towing.
- Minimum sound signaling equipment required on a vessel of 10 meters in length includes a bell and a whistle.
International Regulations Compliance
- Annex III of the Collision Regulations stipulates that whistles fitted more than 100 meters apart should not be sounded simultaneously.
- Fishing vessels use additional signals as specified in Annex 2 of the Collision Regulations.
Vessel Definitions
- "Underway" refers to a vessel not anchored, made fast to shore, or aground.
- A "seaplane" is defined as any aircraft designed for water maneuverability.
Vessel Navigation in Restricted Visibility
- Power-driven vessels such as "A," fitted with radar in fog conditions, must proceed at a safe speed.
- Vessel bearings and distances should guide navigational decisions, especially in proximity to other vessels.
