Why did Samuel Pepys study shipbuilding and naval-store prices in 1662?

In 1662, Samuel Pepys resolved to perform his duties as clerk of the acts of the navy with greater diligence and professionalism. Feeling galled by the superior status and experience of his colleagues, he sought to prove himself their equal by mastering the technical aspects of his position.1

To equip himself for this role, he dedicated his leisure time to learning the multiplication table, attending lectures on shipbuilding, and investigating the market prices of naval stores, such as tar and oil. By gaining this practical knowledge, Pepys aimed to improve his administrative efficiency and save the King money through more informed oversight of naval contracts. This commitment to industry and duty marked the beginning of his transformation into a highly effective naval administrator who would eventually restore the strength of the Royal Navy.2
