Most dictionaries define ferries as boats or vessels that regularly carry passengers and goods over a relatively short distance. The Staten Island Ferry is a prime example, with its 25-minute ride between Manhattan and Staten Island. Closer to Maryland is the Cape May-Lewes Ferry, which carries vehicles and their passengers between the New Jersey Shore and southern Delaware.

It is a much longer trip at 85 minutes but often a timesaver compared to driving more than three hours between the two points. Maryland once had quite a few Chesapeake Bay ferries, too, going all the way back to the 19th-century steamboat era, but regular service faded away as automobiles arrived, modern highways were built, and the first Chesapeake Bay Bridge opened in 1952. There’s now a move afoot to beef up Chesapeake Bay ferry service.

Let’s repeat that. . One would have to get stuck in a truly epic traffic backup at the Bay Bridge to think you might save time.

And then there’s the matter of finding oneself in Rock Hall, whi.
