The Port of Lowestoft is a harbour in Lowestoft in the English county of Suffolk owned by Associated British Ports. It is the most easterly harbour in the United Kingdom and has direct sea access to the North Sea. The harbour is made up of two sections divided by a bascule bridge. The inner harbour is formed by Lake Lothing whilst the outer harbour is constructed from breakwaters. Traditionally the harbour was the site for an extensive fishing industry as well as engineering and shipbuilding companies such as Brooke Marine, Richards and Boulton and Paul.
