Learn how and when to use a stern anchor, teach your crew. Chances are if you never learn to use a stern anchor properly you will be clueless to recognize when others have deployed one.

If there is a dock ladder you do not tie to it or block the path of others trying to use it.

The further you get away from the BVI the more you will see of both.
