You can purchase tickets for the Wm. B. Tennison, online, up to 24 hours in advance of a cruise. Each day at 2 p.m., you will no longer be able to purchase tickets online for the following day. You can purchase tickets in person at the Admissions Desk in the lobby of the Calvert Marine Museum, the day of the cruise, while space is available. The Tennison accommodates 40 passengers and the tickets are first-come-first-served. If you want to check to see how many tickets are still available before driving to the museum, call 410-326-2042, ext. 8068 and ask the Admissions Desk Clerk. They will gladly help you.
The Tennison cruises are at 2 p.m., Wednesday through Sunday, May through the end of October.
