We heard what sounded like explosions. I thought it might be coming from our boat but Lene reassured me it was far away, like last nights thunder. Then came a voice: "Sailboat heading north on the Potomac off Cobb Island, this is Range Boat 4." I acknowledged and he asked me to switch to channel 12 which I did. He asked if we had paper or electronic charts and I said "Both". He said they were conducting naval gunnery exercises and the deep wide channel in the center of the river is where the shells would be landing. He asked me to check my charts and pointed out five navigation aids that hug the Maryland shore. I should thread our way to and through them. We complied cheerfully and while the water was a lot shallower than center channel, it was never less than 12 feet. We heard many explosions, seeming to come in pairs, about two seconds apart: the guns report and the shells explosion upon hitting or its fuse setting it off. This is the orange topped Range Boat One, at the other end of the range, who stopped a crab boat that did not have its radio on.
We passed this nuclear power plant, the smoke or steam rising from it telling the tale of the days wind.
We crossed under the Nice Memorial Bridge on which Route 138 runs.
Once again, with our early start, we went further than originally planned. The guide books describe anchoring in the Port Tobacco River, which flows into the Potomac from Maryland. It is about four miles wide at its mouth and perhaps four miles deep to the village at its narrow end (approximately the dimensions and triangular shape of Hempstead Harbor in Long Island Sound), but most of it is considerably less than six feet deep though there are large areas on both sides near the mouth that are 7 to 9 feet deep, where we could anchor. With winds (though light) predicted from the South, there would be little protection in those areas. Lene discovered a broad underwater plain on the chart, about ten to eleven feet deep, on the Virginia side of the river, near what the chart described as Fairview Beach, about ten miles further upstream and far outside the channel. This likewise provided no protection from wind or waves -- except from the south.
This place was not listed as an anchorage by the cruising guides, but it was very advantageous in dividing the 80 miles to the District of Columbia into two nearly equal passages. The chart described the bottom as "s sh" meaning sand and shells, which is good for anchoring. I asked friendly Range Boat Four about it. He said he had used it so we did too, and the anchor held so well that we had to use ILENEs engine to break the anchors hold on the bottom once we got its chain tightly straight up; the windlass was not strong enough. We were the only boat anchored and had lots of swing room and potential drag room but the scattered thunderstorms missed us and we had a quiet night. The next day we left at 6:30 to catch favorable tide most of the way, making seven knots instead of four. Again, motoring, except when the engine stopped for a few minutes and I had to switch fuel tanks. We passed this strange and unmarked buoy farm on the Maryland side.
The Potomac is huge - long, broad and deep -
and much of its shorelines are undeveloped though some nice houses are built on the bluffs overlooking both sides, including this old one -- Mt. Vernon -- George and Martha Washingtons house, to the left of the big white tent, about ten miles from DC.
Except for the crab boat and one other trawler heading south that we passed near the end of our two days, we saw no other boats except for small runabouts and an anchored derelict boat during our almost 80 miles combined, until we got within ten miles of the Nations Capital, where the waterway had ferry traffic.
The Woodrow Wilson Memorial Bridge, which our charts said was a "bascule bridge under construction", caused us some consternation when we first saw it from five miles downstream. Bascule bridges, after the French word for see-saw, are designed to be opened and from the distance it looked low, so we tried to call on channels 16, 9, and 13 to get an opening, but with no response. Lene then read that it requires a twelve hour advance notice for opening. Oh no! She got a telephone number and called. "Yes, but you are in luck, we are opening for maintenance at 11:30 tonight" was the response. Im saying to myself that this cannot be. We will be having a ten hour wait and then have to enter a new harbor in the dark!! We were told that this new bridge has so much vehicular traffic that it opens only at night. Finally we learned that its vertical clearance, at the white part to the left, which does open, is 70 feet; it is a high bridge that ILENE can pass under without its opening. I had assumed, that all new bridges over major waterways would be at least 65 feet high and many low bascule bridges are being replaced with new high ones so it made no sense to build a low bridge in the 21st century. But it sure looked low from a distance.
We refueled and then docked at the Capital YC, which is under reconstruction, with a series of temporary walkways between the docks leading to its temporary clubhouse in a former motel. We are at the furthest end of the furthest dock, making for a long walk to get out or to the showers, but the most remote dock is a good place for the kitties to roam. We immediately found both the staff and the other boaters here to be quite friendly and helpful. Free coffee, a map with the directions to the supermarket, etc.
Our first afternoon I spent faxing and Fedexing a document to my daughters attorney in Vermont who is helping her sell the riding academy where she has lived and worked for over ten years We also provisioned at a nearby supermarket, washed the topsides and, after dinner aboard, watched a couple of hours of "Wolf Hall" via the Clubs wifi in the clubhouse.
I also contacted my friends, Bob and Maria, who invited us for dinner at their house on Saturday night. I have known them since I worked with Bob in 1970. We last saw at about this time of year in 2006 when they drove to Annapolis to meet up with us there. We are looking forward to spending several sightseeing days in this beautiful city.
