I went up to Pasadena to take a look at Tranquillity Base and move it so it only occupies it own slip (I'd moved it to the middle of the double-wide slip when my slip neighbors were hauled, and then left the dock lines a little looser than normal in case of surge). I had 11 lines rigged -- 5 to cleats and 6 to pilings.
Getting into White Rocks marina was rather interesting. The utility pole at the entrance to the marina broke and fell to a leaning position, and power lines are on the ground. They are primaries (30 KV), and power was clearly secured, but that doesn't mean they are dead. They could have lower voltage -- essentially leakage -- for a number of reasons. I parked a block away and walked in (against the advice of the BG&E folks). The advantage of being an Electrical Engineer is that I know the risk of being around the lines and how to avoid trouble.
TB suffered no damage, although it was a little wet inside. All 11 lines held, although one of the bow lines and its chafing gear is looking a little careworn. Time to replace it. The initial NE winds pushed the cabin roof hatch open a little. I'm glad I had the hasp and lock on it so it couldn't move very much. Still, there was enough movement to create a slot for the rain to get in. It must have been raining nearly horizontally -- the port settee is damp over most of its length and There was still a little water on the cabin sole near the hatch and entryway steps as well as dampness in the galley sink. I mopped the water. The rest will dry in time.
I got to the marina about 12:30, about an hour before low tide. I timed it in case of flooding in Rock Creek and the Patapsco River. The timing turned out to be a needless precaution as the water level was unusually low. The NW winds were blowing all the water across to the east side of the Chesapeake and almost a foot of barnacles were exposed on the pilings. The winds are stlll pretty stiff. I'd guess it was blowing between 25 and 30 kts between the time I arrived and the time I departed at 3 PM.
I'm happy. Overall, the blow could have been much worse and my preparations were sufficient. Besides, I can now conclusively say that the portlights I replaced earlier this year do not leak!

There were no water marks on the wood trailing down below them.
