When his father dies, Jack Aubrey inherits the Aubrey family estate and the role of lord of the manor in "The Letter of Marque". He displays extensive knowledge of the laws and practices surrounding that role in "The Yellow Admiral", when he opposes enclosing the only commons left to the manor. His good connections with his neighbors in Woolcombe gain him a seat in Parliament from the pocket borough held by his neighbor Cousin Edward Norton; gaining that seat aided in his restoration to the Navy List. He sits as justice of the peace for certain local matters. This knowledge and well-tempered judgment seems to match with his skill in running a tight ship, a happy ship, and is a contrast to his financial faux pas. He can earn the money by taking rich prizes, but only with the help of his wife's good management and his lawyer's persistence at winning in lawsuits meant to take it from him, does the money stay in his hands for good uses.
