Re: Assisting boats run aground in mud?
Having been aground myself, I help when I can, (and I am a power boater, mostly).
If in your estimation, and you are the final judge, you would be placing yourself in danger to help, your best move is to offer to call sea tow for them.
Anyone can run aground, you wouldn't want to be in their shoes watching boat after boat stream by while your keel slowly sinks deeper in the mud.
There was a time I didn't go back to help, and it was for that very reason. I got the call at sunset just as I was clearing the entrance to my marina. I had no provision to run at night, and it would have been 3-4 hours of feeling my way back up the ICW in heavy barge traffic past several tricky bends through a bridge, then down the shipping channel, with less than an hour of light left.
And the boat was safe, (engine didn't start after day of fishing), anchored next to sea park, across from US coast guard station, and didn't want to pay sea tow fee. They had Coast guard on the radio, who then relayed request to all boaters.
I didn't go back, if they had called a couple hours earlier, I was actually near them earlier that day, I would have.
Moral don't wait for dark to call for help.
