Sorry, Andy C, but I dont' see anything on your link that discusses the harbor cruise or its schedule. There are explanations of the trolley frequency at various times during the year, but I don't see anything about harbor cruise schedules. Can you be more specific about where I should look for that?

Very sorry for the confusion, there is limited information about the harbor cruise on the website. Cruises are ran by Inner Harbor Cruise. Reservations are not required, and you can use the cruise and trolley ride on separate days if you'd like. Cruises are approximately 45 minutes long, and run once every hour between 10:30-4:30.
