Many collisions happen in restricted
visibility, but the main cause is not poor
visibility but the fact that the OOW
failed to follow the correct procedures
like calling for extra resources, reducing
speed or plotting the target concerned.
This is similar to losing situational
awareness, which means that the OOW
is not fully aware of the factors af-
fecting the vessel at any given time.
Reducing speed would greatly enhance
situational awareness.
