Question 1864Navigation General

The correct answer is C) decrease speed while passing so you won't create a suction. When approaching barges tied off to the shore, it is important to decrease speed in order to avoid creating a suction effect that could pull the barges away from the shore. Passing at a slower speed reduces the risk of the tow's wake destabilizing the moored barges. This is in accordance with best practices and regulations for safe navigation when encountering moored vessels. The other options are incorrect because doing nothing different (A) or increasing speed (B, D) would increase the risk of disrupting the moored barges, which could lead to unsafe conditions.
