Poor visibility collision avoidance
On the ship in poor visibility collision analysis, summarized the main reasothe ship's operations due to poor visibility and greatly curtailed, navigation environment 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 horizontal or close to being horizontal to the formation of course boat smaller orthogonal situation of uncertainty. Data on the starboard side clos
