Two ships moving in parallel paths close to one another risk colliding. Why?

Bernoulli's principle says that when the exact speed of fluid increases, then at the same time, the static pressure and the energy of fluid decrease.

When ships move close to each other, there is a small space between them. The water speed in that region is very high, resulting in the decrease of pressure between the two ships, which follows Bernoulli’s principle.

The pressure between the two ships decreases but the pressure in the outer region of the ships remains the same at its initial value. This process creates the pressure difference between the two regions; one is the region between the ships, and another is outside the ships.

The pressure difference between the regions tends the two ships to collide with each other. Therefore, the two ships moving close to each other are always at risk of colliding.
