No! Advance reservations are not required for the Put-in-Bay ferry boats. The Put-in-Bay ferry boats run on a first-come-first-served basis operating as quickly as one boat every 15 minutes during the peak season and one boat hourly in the offseason. Both ferry services have several boats. Try to arrive early for your trip to Put-in-Bay on the ferry to ensure the best options and shortest waits! Check the Jet Express or Miller Ferry websites for details and schedules.
