Technically, they are both rent. SF marina is City owned and run, so no ownership, but their is a loophole, and people charge more for the boat with the slip attached. Pier 39 is leased from the City by Pier 39 LLC. You can buy the slip for 30 some-odd years, so its basically a lease too. That last one makes no sense to me at all.
