Venezuelan Rescue & Maritime Safety Organisation
ONSA A.C. (The Venezuealan National Rescue and Maritime Safety Organization) is a national voluntary and civil organization which publishes a Boater's Risk Zone Map of dangerous areas. Visit http://www.onsa.org.ve/enindex.shtml# for the link.
In case of an emergency, yachts can activate a private emergency comunication Net for Venezuela & the Caribbean, via email email@example.com which is attended by many voluntary and governmental entities related to Maritime Search & Rescue Operations in the region. This email will activate an alarm in over more than 20 related organizations Caribbeanwide that will open a MSAR mission on your call.
VHF Channel 16 for maritime emergencies: Some times this channel is NOT the STBY channel of some areas or marinas, particularly in the Eastern regions of Venezuela [i.e. Puerto La Cruz]. The coastal radio stations are working only from 8am to 5pm weekdays and from 8am to 7pm weekends; unless private / marinas radios stations upon request.

It should have an operational VHF comunication radio on channel 16 but for now is not confirmed.

ONSA receives from time to time reports of Piracy / Armed Robbery on yachts, anchored at night near fishermen's areas. Mostly this reports are related to drunk or drugged fishermens looking for money and/or personal belongings like towels, shirts, etc. In case of an attack, you should contact immediately the nearest PORT OF CAPTAIN and the National Investigative Police Corp (CICPC), to declare the incident. ONSA can also help & recommend further actions; contact them on firstname.lastname@example.org or email@example.com
