Our Chantey program has been running for 30+ years! Held in the Maritime Museum Building and now once again in the place it all began, in the hold of the CA THAYER at Mare Island, our crew monitor the spaces, set up and and clean up after the event. They also have plenty of time to attend and enjoy the singing.
