Usually the Examination Steamers will fly the blue ensign, but in certain circumstances they may fly the white ensign.

By night the steamer will carry—

(a) Three red lights vertically disposed if entrance is prohibited.

(b) Three white lights vertically disposed if entrance is permitted.

The above lights will be carried in addition to the ordinary navigation lights, and will show an unbroken light around the horizon.

(8) Masters are warned that, when approaching a British port where the Examination Service is in force, they must have the signal letters of their vessel ready to hoist immediately the Examination Steamer makes the signal: “What ship is that?”

(9) Masters are warned that, before attempting to enter any port when the Examination Service is in force, they must in their own interests strictly obey all instructions given to them by the Examination Steamer.

Whilst at anchor in the Examination Anchorage, masters are warned that it is forbidden, except for the purpose of avoiding accident, to do any of the following things, without permission from the Examining Officer:—

To lower any boat.

To communicate with the shore or with other ships.

To move the ship.

To work cables.

To allow any person or thing to leave the ship.

(10) In case of fog, masters are enjoined to use the utmost care, and the port should be approached with caution.

(11) When the Examination Service is in force, merchant vessels when approaching ports are especially cautioned against making use of private signals of any description, either by day or night; the use of them will render a vessel liable to be fired on.

(12) The pilots attached to the ports will be acquainted with the regulations to be followed.

PART III.—MINE-SWEEPING OPERATIONS.

H.M. vessels engaged in mine-sweeping operations or exercises are hampered to a considerable extent in their manoeuvring powers.

With a view to indicating the nature of the work on which they are engaged, these vessels will show the signals hereinafter mentioned. For the public safety all other vessels, whether steamers or sailing craft, should endeavour to keep out of the way of vessels flying these signals and not approach them inside the distances mentioned herein, specially remembering that it is dangerous to pass between the vessels of a pair or group sweeping together.

1. Signals Shown by Day.

a) By vessels working singly—

A black ball at the foremost head, and a similar ball at the yardarm or where it can best been seen, on that side on which it is dangerous to pass. (If a ball is shown at each yardarm it is dangerous to pass either side.)

Vessels showing this signal should not be approached nearer than 900 yds.

(b) By vessels working in pairs or groups—

A black ball at the foremost head, and a similar ball at the yardarm or where it can best be seen, on that side on which it is dangerous to pass.

Vessels should not pass within a distance of 400 yds. astern of a pair or group of sweepers, or when more than one pair or group are working in company, within a distance of 400 yds. astern of the rear pair or group. They should on no account attempt to pass between pairs or groups working in company.

2. Signals Shown by Night.

As for day, except that all round green lights will be used in a similar manner to and in place of the black balls.
