" The boat has algae and all sorts of tiny sea critters ..."
maybe they should re-locate to a more friendly city after the repairs are done ?
I've often thought that having the USS Pampanito, USS Hornet (currently in Alameda), and the USS Iowa (currently in the Mothball fleet in Suisun Bay), at one site would make one heck of a Naval Museum.
However, Pampanito does exceptionally well, right where it is on Fisherman's Wharf. The site is not controlled by the city, but instead is part of the San Francisco Maritime National Historical Park. The boat gets a lot of visitors from all of the tourists that pass through the area. It is the best cared-for museum boat of any that I've visited.
I don't think the Pampanito would do itself any favors by moving anywhere else.
