'Report of a committee of enquiry on the lighting and buoyage of the Persian Gulf. 1909' [‎3r] (5/18)

Both Kais and Shaikh Shuaib being very low islands off high land are
invisible at night.
Kais is most dangerous to a ship altering course to the eastward after
passing Shaikh Shuaib.
A ship bound west can obtain an approximate position to enable her to
clear Kais when passing Farur Island which is always visible on a clear
dark night.
Shaikh Shuaib is most dangerous to a ship hauling up to the northward
after passing Kais. A light on Kais would obviate the danger which that
island presents and give a departure point for clearing Shaikh Shuaib,
but it would leave Shaikh Shuaib an unmarked danger to ships bound
south and east and does not lend itself to any future development of the
lighting system.
A light on Shaikh Shuaib will eliminate the danger of that island, and
give a departure point for clearing Kais on an easterly course.
Taking advantage of Farur Island as a night mark east of Kais, the
lighting of Shaikh Shuaib in preference to Kais is indicated as the best
means of eliminating the danger presented by both islands.
A 15-mile light on the south-west corner of Shaikh Shuaib is therefore
recommended.
The lighting of Tanb is also recommended. Course is altered off this
island which cannot be always clearly seen at night.
A light on Tanb will give a departure point to pass close to the north of
Farur Island and clear of Farur Shoal, and serve as a clearing mark for the
flat shoal off Kishm when making Lingah.
The site selected is on the summit of the island 165 feet above high water,
and near the north-west point.
A 20-mile light is proposed.
No political difficulty is anticipated with regard to Tanb, which belongs
to the Shaikh of Shargah.
The Persian Government would have to be approached with reference to
Shaikh Shuaib or Kais.
Kais and Farur were also visited.
Lingah.
The establishment of a port light to facilitate the approach to Lingah is
recommended. It should be situated at a height of 30 to 40 feet above the
ground in order to be conspicuous by its elevation above the lower lights in
the town, and could be placed in the courtyard or in front of the new offices
of the British India Steam Navigation Company. Local arrangements for
the efficient maintenance of this light can be made.
Ras al Mutaf.
A light at Ras al Mutaf is considered necessary. All traffic from Koweit,
Shatt al Arab, and Bushire, converges on, and rounds this point, and the
establishment of an 11-mile light vessel near the 10-fathom patch south
west of the shoals is recommended. A shore light is clearly unsuitable
owing to the extent of the shoal off the shore,
