Hanging by a thread

Actually, I am not hanging by a thread. I am hanging on an big anchor with a bunch of chain going up to a mooring ball that has three large pieces of 3 strand line leading to two different attachment points on Reboot. Even so, I am pretty sure I will never be comfortable with certain parts of long term cruising.
It has been raining all afternoon. The thunderstorms have abated but a very strong cold front is working its way past Key West. The winds are averaging about 25 knots with gusts into the low 30's. Reboot is bouncing around on the mooring ball, fortunately not enough to make me feel sick. But I am very aware that in the confined space of the Boca Chica marina if the mooring lets go I will have about 10 seconds before my home hits something very solid. Forget the wind in the willows - I can hear the wind howling thru the rigging above my head. It is not a very comfortable way to spend an afternoon and evening. It would be nice at this point to be blissfully ignorant of the physics of the thing but having had Reboot drag its anchor and having watched Gypsysails do the same I have too much information.
I completed the fifth of my five confined water dives (i.e. in a pool!) today. I have already completed the 5 knowledge segments and taken the quizzes and final written exam so all I have left is my four open water training dives for my PADI "Open Water Diver" certification. The weather for tomorrow is not expected to be much better than today so I expect to go out to the reef and dive on Friday and Saturday. I am looking forward to both getting the certification and enjoying this new activity.
I will keep you posted.
