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

A close in to the land wall, keeping the stern in at all times
B wide out from the land wall, keeping the stern in at all times
C close in to the land wall, keeping the stern out at all times
D wide out from the land wall, keeping the stern out at all times
AI Explanation

The correct answer is A) close in to the land wall, keeping the stern in at all times. When approaching a downstream lock with an outdraft, it is safest to stay close to the land wall and keep the stern of the vessel in towards the wall. This helps counteract the effects of the outdraft, which can push the stern of the vessel away from the wall. Keeping the stern in maintains better control of the vessel and reduces the risk of drifting into the lock walls or other obstacles. The other options, such as staying wide out from the wall or keeping the stern out, would make it more difficult to control the vessel in the presence of an outdraft and increase the chances of an accident.
