When steering a tow downstream around the shape of a sand bar, and staying on the proper side of the buoys, an operator should be cautious of __________.

Correct Answer: Option A — eddies below the bar

Water flowing past submerged sandbars creates turbulent, circular rotating waters known as eddies immediately below the bar. These unpredictable currents can compromise vessel steering control, necessitating heightened vigilance from the helm.
