(3) Sunken Rock in Channel North-west of Koh Tron.
Information has been received of the existence of a sunken rock lying in the northern part of the channel between Koh Tron (Phu-Quoc) and Water island, castern shore of the gulf of Siam:-
This danger (Cape Clear rock) on which the British vessel Cape Clear is stated to have struck, was found by a boat sent to examine the locality, to have 4 feet water over a flat summit, yellow in colour, and about 10 feet square; it lies with the following bearings, viz. :—
East extreme of Water island South extreme of Water island N.W. point, Koh Tron
.N. 50° W. .S. 73 W.
..South.
At the distance of about half a cable southward of Cape Clear rock, a depth of 14 feet was found, and at about three- quarters of a cable 23 feet.
(The bearings as given are Magnetic. Variation 2o Easterly in 1881.)
(4) Reported Sunken Rock Westward of Koh Rong.
Also, of the existence of a sunken rock lying about 27 miles westward of Koh Rong, eastern shore of the gulf of Siam This rock (Jan Peter) on which the German barque Jan Peter grounded at 8 a.in. on 21st December 1880, is stated to have 2 fathoms water over it, and as seen from aloft was estimated to be about two ships' lengths in extent; the following bearings were observed from the vessel when aground, viz.:-
Koh Kong summit,
Koh Rong Rong Sam Lem
3"
N.N.E.
E. S. .E. by S.
About 2 hours after grounding, the tide had risen about 10 feet, and the vessel backed off the danger, striking heavily from the easterly swell.
The above bearings would place Jan Peter rock about 22 miles W.S.W. of Koh Samit (nearest land), or in lat. 10° 45′ N., long. 102° 42′ E., but from the nature of the account received, the position must be regarded as approximate. Mariners therefore should navigate in the vicinity with great caution.
(The bearings are Magnetic. Variation 2o Easterly in 1881.)
