Gosport’s physical position at the entrance to Portsmouth Harbour coupled with its 24 miles of waterfront and deep water access to the Solent makes it an ideal location for marine related businesses and leisure activities.  Its close proximity to Portsmouth Naval Base also means that there are long established links to the Royal Navy and significant MoD and private sector defence related operations in Gosport too.

As a result it is home to a significant number of marine related businesses made up of local, regional, national and multinational firms, with the latter including UK HQs.  There are also a large number of engineering and manufacturing SMEs that service marine supply chains, as well as other sectors such as aerospace and automotive.

The marine related businesses based in Gosport include:
