When draft exceeds...

...depth, you're aground!

Meh, could've been the tide if it's saltwater. Could be flood control and dam releases if it's fresh water.... could be a drought.

... a boat that needs both a depth gauge and an altimeter.

Saltwater. I saw her come in and stop dead. She must have hit bottom. This was right around high tide. Then the tide went out. It's harf to see in the picture but she is completely out of the water.

Bertha has left the beach! Must have happened at high tide during the night.

Looking at the pic, I'd modify the title to "When depth = zero, you're aground".

seems to happen twice a day in these parts!

That's how we cleaned the boats bottom in De.
Had a 40ft sailboat and would take it up the Broadkill River.
Wait for the tide to go out and clean the hull on one side.
Then wait for the next tide to do the other side.

Looks like around DIGBY, Bay of Fundy, Canada. Tide changes in the tens of feet. Have been to Annapolis Royal, NS. and observed several times. [h=1][/h]
