Regulation 4 Accidents happening to pilots
An accident happening to a mariner employed as a pilot who normally plies his trade as a pilot from a port in Great Britain shall be treated as arising in the course of his employment if it happens—
(a)
while, with a view to carrying out his duties as such pilot, he is on board or is embarking in or disembarking from any ship or vessel; or
(b)
while, having left such ship or vessel at a place other than the port from which he normally plies his trade, he is returning without undue delay to that port.
