Gaston showed up with his assistant promptly as scheduled. I had cleared out the aft cabin to give access to the area of concern. He laid a pencil on the shaft, so light that it would easily detect vibration. Nothing. It does not happen at the dock, even when, tied onto it tightly, we run the engine in gear up to 2500 rpms, trying to drag the dock. He dissembled the flexible coupling again, tested for alignment with feeler gauges, reassembled it and pronounced that it was within tolerance. So the problem is outside the boat, at or near the propeller end of the shaft. He suggested that we wait until the fall and when the boat is hauled, we check the cutlass bearing and remove the propeller and ship it to California for what will be an expensive reconditioning job. He said that we are not in danger from the current situation.
Then he lent us his truck and we visited the supermarket, the drugstore, and a law firm where I signed a document and got it notarized. I spent a few hours planning the places we could stop along the Potomac on the way up and down to Washington DC. It is slim pickins for anchorages and marinas with water deep enough for ILENEs 58" draft. I have asked the 6500 members of a "private group" on Facebook for more information.
Later Gaston came over and paid us a social visit. He was born in France, raised in Israel and is an excellent mechanic. He was affiliated with and sailed in the Caribbean 1500.
The weather has been rainy most of our two days here and so we did little. I had visited the nautical museum and lightship in 2012 and toured the historic district. It rained then too!
They also have a Childrens Museum and one honoring Virginia athletes. I took a pass on those. There is a small Jewish Museum and a historic 1812 house, both of which can be toured, but only in season, not now.
So we took showers, took on water, cleaned the boat, blogged, read, cooked, ate and watched the first two episodes of the PBS series Wolf Hall, based on a novel by Hillary Mantell, which my book group read a few summers ago, about Thomas Cromwell, an attorney in the time of Henry VIII.
We would have left the second of these two days but the forecast of rain and 25 knot wind in our faces deterred us and the forecast came true.
