Never leave the anchor without a trailing scotchman, does not need to be as big but its safer picking up and reclipping to a line without the anchor stress on it. Also tells you dirrection of your drift when drifting, you can plan drifts better to work the bottom. I have had both go down, think east race, can be scary. Everyone should mark their anchor, name and number, I have personnaly returned 3 that were found drifting. Recieved nice bottle of wine for the return of one.
