That's a serious commitment to hydration.
Sudden, intense hydration.
I got caught in something like that once around the mouth of the Mississippi in a 16 ft fishing boat. It nearly sunk us in the shear volume on rain. We could not bail fast enough. Ended up trying to get the boat on plain and then pulled the drain plug. Couldn't see where we were going and nearly hit another boat. Fun times...
