It is the master's responsibility to continuously assess the risk of collision with other vessels.
Power vessels must give way to:
<< Sailing vessels.
<< Vessels approaching head on (by altering course to starboard)
<< Vessels approaching from the right (starboard) hand side (ie, crossing)
<< Vessels displaying special lights and signals that mean right of way
<< Large vessels restricted in their manoeuvrability
<< Any vessel being overtaken
<< Vessels engaged in fishing activities and showing appropriate signals
A vessel drifting is deemed to be underway and has no special right of way. It is required to comply with the International Regulations for Preventing Collisions at Sea.
Do not create a dangerous situation by forcing your right of way. Always keep a safe distance off other vessels so the vessel can be stopped or manoeuvred to avoid any sudden danger.
The faster the speed, the greater the safe distance must be.
When altering course, make your intentions clear to others as early as possible.
NOTE: In a collision, all masters involved can be held responsible even if the give-way vessel does not give way, because all masters are required to exercise caution and take avoiding action if the other vessel does not.
