That clarified it to me. If you are aground, three bells, rapid ringing, three bells.
If you are aground and have dropped an anchor, you add the gong. You can add the whistle.
When one is aground, in a ship of over 100ft, life is complicated. Make as much noise as you can, in Fog. One doesn't want to add to the woes.
