[ASIA-SINGAPORE] Straits of Durian Sugi and Chombol.

Early issue of this rare Hydrographic chart  of the new surveys made in 1900 with small corrections to 1912. The  map covers the area between Singapore and the east coast of Sumatra between Kundur and Buland Island, with good detailed information of the islands of Sugi, Caitlin and Sugi Bawa.

The regular updating of Hydrographic charts by the Hydrographic Office was to ensure that commanders of ships, pilots and other mariners were able to have the most to up to date information available to safely navigate foreign waters and ports as new information of changes to sea depths, sand bars, wrecks or other any other pertinent nautical information that could hinder passage became available. As updated charts were offered for sale, the earlier outdated charts in the hands of mariners, pilots, ships owners and sailors were invariably discarded, subsequently making all British Admiralty issued hydrographic charts of the period rare.
