Question 1867Navigation General

The correct answer is D) the tows will tend to drift together. When two vessels are passing close alongside each other while pushing ahead in the same direction, the phenomenon known as "suction" occurs. This causes the two tows to be drawn together due to the pressure differential between the vessels. This suction effect can make it challenging to maintain a safe distance between the two tows, and it is something that vessel operators must be aware of and manage accordingly. The other options are incorrect because A) the tows will not tend to drift apart, as the suction effect draws them together, B) you will not necessarily gain speed, and C) both boats will not necessarily gain speed, as the suction effect is the primary factor affecting the vessels' movements in this situation.
