What does Hester learn from the ships captain in The Scarlet Letter?

Hester learns that Mr. Chillingsworth, her husband, is planning on going to Europe with Hester, Pearl, and the Reverend. This is disturbing to Hester because Mr. Chillingsworth is really her husband, and for the past seven years has been giving "medical" treatment to the Reverend. Mr. Chillingsworth is using this in order to enact revenge towards the Reverend since he knows that the Reverend was Hester's lover.
