ACS element text (the applicant demonstrates understanding of)

Depart the dock/mooring buoy or beach/ramp in a safe manner, considering wind, current, traffic, and hazards.

Bottom line

Keep in mind that when taxiing in the same direction as the current, directional control may be reduced because the seaplane is not moving as quickly through the water.
