The proper way to approach a downstream lock where there is an outdraft is to be __________.

Correct Answer: Option A — close in to the land wall, keeping the stern in at all times

Outdrafts at downstream locks pull vessels away from the guide wall. Approaching close to the land wall allows the vessel to use the wall as a buffer. Keeping the stern in prevents the current from catching the quarter, which would otherwise swing the vessel uncontrollably into the lock approach.
