Notice to Mariners

Fortunately for us, reefs take thousands of years to form and bathymetry changes are rare.  Man made changes however are sudden and can affect mariners.   Please add the following (3) man made additions and (1) geological addition to your guide.

Page 77:   Entrance Enlarged – The artificially cut channel entrance to Wangi-Wangi lagoon previously had a depth of only 2.1 meters at high tide.  This channel entrance has now been dug down to a much greater depth as well as widened and can be entered on all tides.  Depth now is 4 meters at mean lower low water.  Two visible red and green beacons mark the entrance as well as two orange buoys marking the outside and inside edges of the reef.  Red and green markers are NOT lit at night.  A jetty is currently under construction along the north side of the channel.  Jino, the local yacht helper will be available on Ch 16.


Page 81:   Bridge Construction – Ambon harbour outer anchorages (A) and (B) are unaffected and remain as written in the guide.  The inner harbour area of Halong Bay, Ambon now has the Merah Putih Bridge spanning its entrance.  Inner Ambon harbour anchorages (C) and (D) are only accessible for yachts able to pass under this height restriction.  Err on the side of caution when approaching.



Page 174:   Anchoring Restrictions – Gili Trawangan, Gili Meno and Gili Air have been designated as an MPA (Marine Protected Area) and anchoring has been forbidden.  The image shows the MPA boundaries in Light Blue and designated harbour areas in Dark Blue. It is recommended to use moorings only and not anchor anywhere inside the MPA until further clarification on this matter is given by authorities.



Page 210:   Volcanic Eruption – Anak Krakatoa lost over two-thirds of its volume with the latest eruption and its elevation above sea level has been reduced from 338 meters to 110 meters.  Lava flows have covered much of the island and its surrounding waters and the anchorage has mostly been covered by fresh lava.  For the moment, we would not recommend viewing Anak Krakatoa in such proximity.




End of corrections.
