Navigation Officers must build this data into their Passage Plans, allowing for possible depth changes and missing navigational marks. It is suggested that the sounder/sonar be operated continuously, give land masses a wider berth than usual where possible and obtain navigational data from the Armada de Chile prior to entering Chilean waters. The Consular Officers of Chile may have useful data however it must be realised that there has not yet been the opportunity to survey for chart corrections.
Mariners may find that at this time and for some time in the future areas may be closed to shipping particularly private yachts and cruise ships. Search and Recovery is underway.
Full cooperation with the Armada de Chile is necessary as the country has a lot on its hands at present. Also there is an Administration change on March 11, 2010. Obtain, read and follow all SHOA 'Notices to Mariners' regarding Chilean Waters.
