Introduction

A man in colonial period naval uniform carries a large navigation device in his left hand and a bag under his right arm. In the background is a large body of water, upon which is a vessel.

In the 1700s traditional instruments which helped to guide and track vessels were improved and new ones were invented.

With no land borders, Britain's defence budget flowed mostly to the navy.

Much time and money was spent solving the optical, mathematical, astronomical and practical challenges that had constrained long-distance sea voyaging for centuries.
