I have seen boats proudly displaying as anchor attached to a thin(1/4") frayed, kinked and knotted length of yellow nylon rope that I wouldn't even feel safe tying a poodle up with! :shock:
As for drogues - if you don't have 1 on board and loose power in conditions too rough and deep to anchor, you can fashion 1 from a pair of pants. Do up the zipper and button. Tie a knot in the bottom of each leg, tie 1 end of a length of rope to a belt loop on 1 side and the other end of the rope to a belt loop on the other side then fasten the middle of the length of rope to your bow cleat. It may not be as effective as a properly sized drogue , but in a pinch it offers some sea anchor protection.
If your a size 58" waist you might be OK! It might be a little chilly and embarrassing though waiting for help to arrive in your briefs!
