These Regulations implement Chapter V of the International Convention for the Safety of Life at Sea, 1974 (“the Convention”) (as amended to date), relating to the safety of navigation of ships. The Regulations revoke and replace the Merchant Shipping (Safety of Navigation) Regulations 2002 (as well as other instruments which amended those Regulations) and apply, with certain limited exceptions, to United Kingdom ships and to non-United Kingdom ships when in United Kingdom waters, including ships from countries which are not parties to the Convention (regulation 3).
