Two vessels are abreast of each other and passing port to port in a confined waterway. What should you expect as your bow approaches the screws of the other vessel?

Correct Answer: Option C — Your bow will sheer towards the other vessel.

As your bow approaches the other vessel's stern, you enter the low-pressure wake created by their propeller. This suction effect pulls your bow toward the other vessel's centerline. Proper helm application is required to counteract this interaction and maintain a safe passing distance.
