NOTICES TO MABINBBS 243
VESSELS NAVIGATED STERN FOREMOST.
Such vessels display two balls, each 2 feet in diameter, carried at
the ends of a horizontal jackyard on the mast or, if the vessel has more
than one mast, on the main or after-mast. The jackyard will be placed
in a thwartship direction, at least 6 feet higher than the funnel top, and
will project at least 4 feet on either side of the mast, so that the distance
between the centres of the two balls will be at least 8 feet.
Bye-laws giving effect to this arrangement have been made for the
ports of Dover, Bamsgate, Holy head, Larne and Belfast.—July 23,
1930.
SUBMARINE CABLES.
Should a submarine cable be lifted to the surface by a vessel heaving
up anchor she should pass the end of a 5-inch manila rope (do not
use wire) under the cable, make the end fast inboard, haul the rope
tight and hang the cable on the bight of the rope, then lower the anchor
clear of the cable which can then be slipped. The fouling of a cable
together with the position as accurately as possible should be reported
the nearest cable station.
Skippers of trawlers are urged to exercise care when trawling near
telegraph cables, and if a cable is fouled great caution should be exercised
in attempting to clear it. It is advisable to sacrifice the gear rather
than to exert force in freeing it. Compensation for loss of gear is made
on a sworn declaration being made and upheld.
SEINE NET FISHING BOATS SHOW.
By Day.—One black ball or basket in the forepart of the vessel and a
black cone or triangle, apex upwards, at the mizzen yardarm* Pass
her on the clear yardarm side.
By Night.—Three white lights in a triangle, apex upwards, from the
yardarm on the Side from which the gear is leading. She exhibits her side-
lights when running out the gear, but no side-lights when hauling it in*
Sound Signal.—Seine net vessels give 4 blasts, 3 long and 1 short,
on the whistle (— — «••• *) when approached by other vessels. In
fog, seine net vessels give the same signal as other fishing vessels.
These special lights and signals are given to warn vessels off their nets
as the warps and gear may be as much as a square mile in extent.
When flares are displayed by a fleet of fishing vessels on being
approached by another vessel they are warning her ofi their nets. It
is necessary to give them a wide berth as a train of nets may extend
over an area of one square mile.
