Ice-breaker as Light-vessel.
After the removal of the lightship Taku, on or at any time after the 1st December, her place will be taken for the winter season by an ice-breaker showing the following signals:-
By day-A black spherical day-mark.
By night-A white light flashing every 12 seconds, thus :--

Eclipse
***
1.5 seconds 10.5 Seconds
and visible in clear weather all round the horizon for a distance of 10 miles.
During foggy or thick weather a gong will be sounded at intervale of one minute when the fog signal of a vessel in the neighbourhood, showing that she is under way,
is heard.
Ice Conditions.
When ice exists, information concerning conditions will be telegraphed to Chefoo and Dairen. Vessels bound for Taku should call at one of these ports for it.
A vessel arriving off Taku, whose agent has given the necessary notice as laid down. herein, will, if conditions permit, find an ice-breaker with pilot on board awaiting her
arrival.
An ice-breaker will, if necessary, lead the way in, and, in doing so, will make such instructive signals concerning the steamer's action as the ice-master considers desirable.
A vessel following a conducting ice-breaker is expected to obey the signals made by the ice-breaker. In the event of a vessel failing to obey the lawful signals of the ice- breaker, unless for reasons beyond the control of those navigating the following vessel, the owners or agents of such vessel will be treated in accordance with Article 29 of the Harbour Regulations.
It should be clearly understood that the Harbour Authorities, under whose control the ice-breakers operate, incur no responsibility in respect to accidents which may happen in the process of following an ice-breaker. A vessel accepting the services of an ice-breaker in the above conditions does so always at her own risk.
