KHM Portsmouth

Port Information

Portsmouth is one of the busiest harbours in the country with the grand total for significant movements being around 130,000 a year. There are also around 5000 recreational craft which moor in the harbour and many more visit each year.

In 1865 the Dockyard Ports Regulation Act was passed, giving KHM extensive powers. The main purpose of KHM is to oversee and enforce the Act. Cascading from this piece of primary legislation is the Order in Council relating to KHM’s area, The Dockyard Port of Portsmouth Order 2005. Together, the Act and the Order provide KHM with powers to issue directions to all vessels within the Dockyard Port, be they commercial, private or military. The powers of the KHM are also delegated to specifically authorised Deputies and Assistants, including VTS Supervisors.

The limits of the Dockyard Port cover not only Portsmouth Harbour itself, but also includes all the waters from near Cowes in the West to Hayling Island down to Sandown Bay in the East with the single exception of Bembridge Harbour. The Naval Base itself comprises only a small part of the geographical area of the Dockyard Port.
