Regulation 3 Application
These Regulations shall apply to accidents involving or occurring on board–
any United Kingdom ship, except that regulation 5 shall not apply to pleasure vessels; and
any other ship within the United Kingdom or the territorial waters thereof, save that regulations 5 and 7 shall not apply to such a ship unless she is within the defined limits of a port in the United Kingdom or is employed in carrying passengers to or from a port in the United Kingdom.
These Regulations apply to serious injuries and hazardous incidents as they apply to accidents, except that:
regulations 5 and 7 shall not apply to hazardous incidents; and
regulations 5(1) and 5(3)(a) shall not apply to serious injuries.
An investigation may be held under regulation 6 into an accident involving or occurring on board a ship which is not a United Kingdom ship and which at the time of the accident was not within the United Kingdom or the territorial waters thereof, if the Secretary of State so determines.
