Notes:
IN THE VICINITY OF ONE FATHOM BANK THERE IS LIMITED NAVIGATIONAL AIDS AS THE DISTANT SHORE LINE DOES NOT GIVE ADEQUATE RESOLUTION FOR RADAR AND ONLY TWO LIGHTS MAY BE VISIBLE AS YOU APPROACH THE TSS ENTRANCE ( BOTH MARK THE NORTHERN EXTREME OF THE TSS AND ONE IS ALSO A RACON).
ONCE WITHIN 5 NM OF THE STRAIT ENTRANCE THREE ADDITIONAL LIGHTS MAY BE VISIBLE (TWO MARKING THE SOUTHERN EXTREME OF THE TSS). THE CLOSEST IS NOTED ON THE CHART AS “LIABLE TO DRIFT” AND THE GREEN SOUTH EASTERN MOST LIGHT IS ALSO A RACON.
NONE OF THESE LIGHTS AND RACONS CAN BE CONSIDERED RELIABLY MAINTAINED.
TRAFFIC IN THE VICINITY OF SINGAPORE IS EVEN HEAVIER THAN THE NORTHWESTERN ENTRANCE TO THE STRAIT.
THE NORMAL TRAFFIC PATTERN THROUGH THE STRAIT DOES NOT FOLLOW A DIRECT ROUT BETWEEN THE TWO TSS’S. NORMALLY TRAFFIC FOLLOWS A ROUGHLY SEMI-CIRCULAR PATH TOWARD THE SOUTHERN HALF OF THE STRAIT.
