Pepys learned arithmetic from a private tutor and used models of ships to make up for his lack of first-hand nautical experience, and ultimately came to play a significant role in the board's activities. In September 1660, he was made a Justice of the Peace; on 15 February 1662, Pepys was admitted as a Younger Brother of Trinity House; and on 30 April, he received the freedom of Portsmouth. Through Sandwich, he was involved in the administration of the short-lived English colony at Tangier. He joined the Tangier committee in August 1662 when the colony was first founded and became its treasurer in 1665. In 1663, he independently negotiated a £3,000 contract for Norwegian masts, demonstrating the freedom of action that his superior abilities allowed. He was appointed to a commission of the royal fishery on 8 April 1664.
