Storm Avoidance - Crew calling the DPA

Here’s the post from the other thread.

This is also a good part of the reason we use such tools as anchor circles and the like.

Sometimes it’s hard to tell for sure if the anchor is dragging or not. So firstly the mate might wait to call until he is 100% sure. Secondly, if the mate is not sure the message might be vague as the mate tries to describe his uncertainty and the message will be made even less clear, seemingly less urgent, if it is mitigated.

With the anchor circle (or similar tools) the ship is either inside or outside, the decision to call is easy and the message is clear, the ship is outside the circle.

In this case "ship’s planned track is inside the forecast 64 kt. wind field (for example) is clear and unambiguous.
