Hi, Would like to know a point about passenger ocean line discharge at NYC piers circa 1850. Most ocean terminal piers and wharves on the East River were used by sailing vessels, while steamers mostly used the North River. However, is anyone aware of steamships having used piers in common with sailing ships, or was there a prohibitive aspect to this? (This question relates specifically to the Black Ball Line's only steamer (SS United States). Am trying to determine if they had to dock it elsewhere other than their regular sailing ship pier 23, now the site of the South Street Seaport.) E M
