After the anchor has set and adequate rode has been paid out, take time to ensure you are not drifting. And considering changing winds and tide height and tidal current, it is important to periodically monitor how well your anchor is set.
Check your anchor set manually and electronically. Do this manually by sighting bearings to objects on shore and determining that they are constant. Note that the boat will swing back and forth with the wind making it a little difficult to check that you are remaining steadfastly connected to the bottom. But, over time, you will get a feeling that through each successive swing, bearings to objects on the shore are not changing.
Using an electronic means will give you a more accurate determination of anchor set. If you have a GPS device, turn it on and turn on “show track.” Observe over time the history track of your boat. If the tracks overlay each other then you are holding steadfast. You can also use an anchor alarm on your depth meter. To do this, you set the maximum and minimum allowable depths. If the depth goes out of this range, the alarm sounds. There are also Apps for your mobile device. Here are a few:
