how do raise a mirror if she turns turtle

have heard various ideas on righting a turtled mirror,but none seem practical especially on the sea.
Has anyone experienced this and if so how did you get her up?

The one time it happened to me, I tuned the Mirror into the wind, and then stood on the gunnel and grabbed the dagger board and pulled with all my might. Then as the sail worked its way up and parallel to the water I continued righting the boat in the usual manner; stepping on the dagger board and grabbing the gunnel.
