The National Register of Historic Vessels and National Archive of Historic Vessels
The National Register of Historic Vessels (NRHV) is a database that lists vessels that are: :*At least 50 years old :*Demonstrably and significantly associated with the UK :*Based in UK waters :*More than 33 ft (10.07 metres) in
length overall (length OA) measured between the forward and aft extremities of the hull overall excluding any spars or projections. :*Substantially intact Inclusion on the Register is with the owner's consent. The records include details of designer, builder, dimensions, construction, propulsion, service history and current location, as well as images of many of the vessels. The National Register of Historic Vessels contains a sub-group of some 200 vessels that comprise The
National Historic Fleet. These vessels are distinguished by: :*Being of pre-eminent national or regional significance :*Spanning the spectrum of
UK maritime history :*Illustrating changes in
construction and technology :*Meriting a higher priority for long term preservation The National Historic Fleet may also include vessels from the National Small Ships Register that are a minimum of 50 years and fit the above criteria.
The National Archive of Historic Vessels includes details of vessels no longer on the NRHV because they have been scrapped, lost, or moved abroad. It also includes vessels that do not meet all the criteria for inclusion on the NRHV but are nevertheless of historic interest. There are currently over 1500 vessels on the National Register of Historic Vessels and over 400 vessels on the National Archive of Historic Vessels. The registers provide an authoritative assessment of the significance of historic vessels. The database can also be used to identify and prioritise vessels that should be preserved, provide guidance to decision-makers on the allocation of funding, and give an early warning of ships 'at risk'. The database can also be a useful research tool, although confidential information about ownership etc. is always kept secure. Over 57% of historic vessels recorded on the National Register of Historic Vessels are either privately owned or commercially operated. Museums and charitable trusts account for 14% of the total. Fully searchable versions of the databases (excluding ownership information) are available on National Historic Ships' website. ==See also==
