How could the changes in fluid speed and pressure lead to collision of the two boats are sailing side-by-side in narrow space?

Changes in fluid speed and pressure can create variations in the water flow between two boats sailing side-by-side in a narrow space. If one boat accelerates, it can generate a high-pressure zone in front and a low-pressure zone behind, leading to turbulence. This turbulence can destabilize the other boat, causing it to drift or collide with the accelerating vessel. Additionally, if the fluid dynamics change rapidly, it could create unexpected currents that push the boats toward each other.
