When I was a boy (1950s), the ship The Island Mail ran aground on an uncharted rock in Puget Sound just inside the Straits of Juan de Fuca. According to my father who was the insurance underwriter and had to visit the stricken vessel, the rock was common knowledge to harbor pilots. They came aboard at Port Angeles. The pilot (who shall remain nameless as I know his grand niece) in this case knew or should have known the location of the rock. I don't know or recall if he was censured in any way.
Decades later, after the city fathers had been arguing about as long over the need for a new high-level bridge over the Duamish River (functionally similar to the Ohio in the Baltimore case), the same pilot was in the wheelhouse of a ship that struck the pier on which was mounted the turntable for the movable span of the Spokane Street bridge. The strike knocked the pier just enough so the span could be swung only with great difficulty. The ships master was known to have a drinking problem and the pilot was IIRC by then 89 years old. He retired immediately afterwards. His niece pled no comment when I asked her about it at the time.
The city council finally relented and approved the bonds to build a new bridge but only on the cheap.
Three decades later that bridge was closed for more than two years while repairs were made to steel-reinforced concrete that hadn't been properly sealed during construction. There was litigation in all three cases. There will be litigation in Baltimore. There will be a new bridge in Baltimore.
Will they finally require tugs in Baltimore? There is a great movie, "Tug Boat Annie" (Annie Foss) starring Marjorie Main, made in 1933 about the rescue of a passenger liner from the Straits of Juan de Fuca. The tug used in the movie was the Aurthur Foss, a coal-burning steamer. With the proceeds from the movie rental Foss repowered the tug with a diesel making it one of the most powerful ocean-going tugs on the West coast. In 1941 it narrowly escaped being bombed by the Japanese near Midway Is. after towing a floating dry dock from San Francisco to Hawaii, then fuel and supply barges on to Midway. There is a long Wikipedia article about the Aurthur Foss. These tugs earn their keep or did in the day when economics allowed it. BTW the Aurthur Foss still sits on Lake Union in Seattle and last I knew was still operable.
