Blair's Harbour

Blair's Harbour is located between Pahang on the east coast of Peninsular Malaysia and the island of Tioman. It never seems to have had any physical presence, but appears (sometimes without the apostrophe or the 's') on many maps of the East Indies/East India Islands/Malayan Peninsula during the 19th century, and still appears on Admiralty Charts.

Alexander Dalrymple of the Hydrography Department of the British Admiralty published a plan of this location on 9 February 1793. The surveyor was Lieutenant Archibald Blair of the East India Company's Bombay Marine.

On the plan Blair's Harbour is described as:

Bearing 11 ¹⁄₄ S of the South End of Po.Teoman 10 leagues Lat.2°43‘N It is very secure being skreened from both Monsoons, and is easy of access the bottom a stiff clay. The water is good and may be had in abundance by making Wells 5 feet deep 20 or 30 yards from high water mark.

A later description of Blair (sic) Harbour is just "The channel between Tanj.Peniabong and Keban I., N.Johore".
