I use it every time but, you know, here in Italy we like to lie in the sun!
The common rule is 1:5 (1 meter deep 5 meters line) but depends by wind and waves
You are talking about proper anchors mate
This thread is about Drogues, I see the confusion as they are sometimes misleadingly called "Sea Anchors"
Drogues are an underwater type of parachute of differing sizes according to length and wheight of boat and how much effect you want it to have.
Often used for drift fishing to slow the drift and keep the boat on an even heading. Fly fishermen use them a lot.
I use one when drift fishing from my Kayak.
