impact on the safety of navigation also pose a great threat.
The fog, the ship's operations due to poor visibility and greatly curtailed, navigationenvironment becomes more complex, another long continuous visibility of the case in
sailing, watch the master and pilot heart stress, easy high tension , physical decline,
thinking and ability to judge and give rise to hasty, blind, hesitant, there are chances, poor
response at the critical moment, critical thinking abnormal, easily lead to the occurrence of
fog.
Also, the fog, the human visual, auditory and navigation equipment will have been
affected to varying degrees, thereby affecting the driver of the navigation area, the
surrounding environment and the right to judge the dynamic impact on the ship route
makes drivers, position to judge the accuracy and reliability, resulted in the effective
control and the ship speed of tickets, not early warning, collision risk situations such as the
right to judge, when taking avoidance measures are likely to lead to misjudgments, it will
cause a serious collision between ships.
Therefore, the fog effect for the safety of navigation is very large, must be highly
vigilant.
Encounter situation in a variety of law of the uncertainty avoidance action
Encounter in various situations, the starboard bow close to the driving situation on
the starboard side and is horizontal with the boat around to the formation of large angle
cross-encounter situation, two ships avoid the uncertainty of the greatest action on the
case of a situation or close to the case of , two ships of the minimum uncertainty
avoidance action. Usually ships from it than from starboard to port overtake overtake
small uncertainty avoidance action. Front to form a small angle cross-ship situation, than
are hor
