37. You have arrived at your anchorage location. You have put the engines astern prior to letting go the anchor. How will you know when the vessel has stopped making way?

The backwash of the propeller reaching amidships indicates the vessel has stopped making way through the water. This is a direct observation, unlike Doppler logs which can be inaccurate due to external factors, or bearings which do not guarantee a lack of water movement. Confirming the absence of headway through the water is crucial before anchoring to prevent dragging or uncontrolled chain deployment.
