Navigation rules ensure safe travel on water. They are the one maintaining order, and making sure that the watercraft knows where to be, with the accurate speed, and what to do in case of emergencies.
These rules can be ignored in some instances, such as:
To avoid immediate danger
Sometimes accident can occur quickly and without warning. Navigators are trained to pay attention to the currents and winds in order to avoid dangerous situations but some are inevitable. In case of an emergency, a captain can go against normal navigation procedures because he has the power to make decisions.
Crossing dangerous water
This can also lead to disregarding of navigation rules. In turbulent waters people hardly think of navigational rules because they are on edge and they will do anything to return safely and that includes bending some navigation rules.
When a vessel has little maneuverability
In this case, the captain and the crew may be tempted to disregard navigation rules to remain safe. Sailing in a vessel with more maneuverability towards one with less agility, the inability of the other vessel to actively avoid a collision must be taken into account, so some of the navigation rules can be overlooked.
Sailing in poor visibility
For example, the use of radar can be complicated or even impossible in low visibility. The sailor’s inability to see clearly may make him to caution to the wind and wing it doing so could result in hazardous situations, so he has to be cautious. So overlooking of navigation rules can happen in case of Sailing in poor visibility.
When the sailor is inexperienced
Navigation is an important skill for any sailor but it can be quite challenging when weather conditions are poor and the captain is unfamiliar with the area. Navigation rules may be disregarded to save time, in case of inexperienced sailors.
