Gubal Island. Middle of the Red Sea.
We moored up there as a big storm was coming in.
We did a night dive.
It was a howler.
The current took three of us.
We came up half a mile or more away on another boat's mooring line*
About 3-5 knots, at night, at c20M? I seriously considered that we were going to die that day.
* I have never been so happy to see anything in my life. The diagonal white line across my field of vision [it's mooring rope] appearing in my torchlight as we howled towards it. I've only had this happen twice in diving so far. You get back, you're kinda quiet, you have a kinda rye-smile, you sit just kinda squinting at each other... 'Yes, we made it, but let's not do that again eh!'...
