Anyone tried it?
Try to look at a sea anchor like a steel
anchor. Properly matched to boat it basically "anchors" you in one spot. All I have read indicates very little "dragging". 24 hours in a storm and maybe a few miles. So lets just pretend it is zero. Finer math can be done during the storm - while comfortably on the sea anchor.
If you are anchored to column of water
then whatever way the column is going is the way you will be going. 2 knots S is 2 knots S. Then apply the finer math ("drag").
That is how I see it never having used one.
