The Mentality
I DONT NEED IT
THE COST
NOT NECESSARY
Of course, this is not a dig at anyone but this can be the mentality of people that don’t get the hole safety thing. However, you would never catch me at sea without the following three bare essentials. I understand that there are a lot great safety items out in the market today but this blog is putting away the full system and stripping down what I would say is the musts on any vessel for your marine electronics onboard. In a nutshell don’t go the too sea without these.
You should get the safty sorted first
The VHF/DSC - First point of safty
First point of safty
Calling out for help direct call to the surrounding area via vocice.
Sending a DSC Call can be used if the current state is not life threatening
Pushng the Distress Button whch sends out a distress call showing your current position and type of DSC disress call(this is not a rotine or test call )
VHF/DSC Voice Emergancy - Channel 16
Channel 16 is the universal emergency channel, constantly monitored by coastguards and other nearby vessels as the default channel that the VHF/DSC
sets are to be left in is this channel(channel 16). It is the point you shout for help and everyone in the area will hear you rather than just the one
person you try to contact by phone.
VHF/DSC Digital Selective Calling - Channel 70
Channel 70 is exclusively for DSC calling for safety and emergency and must not be used for other purposes. The action normally with a red cover can be delatched
exposing the distress button once pressed instantly sends a digital distress alert to the Coast Guard via VHF point to point transmission range.
The SART - Second point of safty
Grap SART…
secure to the life raft
activate if vhf call successful
activate if DSC successful
Shows your position as an AIS target or cycinercal rings via radar or plotter with chart radar overlay
Wait if not…
Marine Rescure and Search SART - Type AIS
AIS (Automatic Identification System) is a system that transmits a ship’s position so that other ships are aware of its position it is designed to transmit AIS messages that indicate the static and safety information of the unit during distress. An AIS-SART has an integral position source and accordingly, AIS stations receiving the AIS-SART signal are able to display the range and bearing
Marine Rescure and Search SART - Type Radar
The radar-SART is used to locate a survival craft or distressed vessel by creating a series of dots on a rescuing ship’s radar display.At some point in each sweep, the radar-SART frequency will match that of the interrogating radar and be within the pass band of the radar receiver.
The EPRIB - Third point
Grab EPRIB…
To be used if all above fails
To be used in conjuction with above also
When activated shows current postion and forwards this on the to search and resue
transmitts to the nearby helicotor on a different frequcy used by the helicotor
EPRIB Emergency position-indicating radiobeacon - With GPS
An emergency position-indicating radiobeacon is a type of
emergency locator beacon, a portable battery powered radio transmitter
used in emergencies to locate airplanes, vessels, and persons in
distress and in need of immediate rescue. When activated the EPRIB transmits the pre-programmed details to a saturlitte via 406MHz how ever EPIRBs with the GPS feature have a location accuracy of 100m – 120m.
EPRIB Emergency position-indicating radiobeacon - Without GPS
Without GPS capability in your EPIRB, the location accuracy extends out to 5km.
If aircraft resue is involved the EPRIB also transmits a 121.5KHz signal which helps to localise the area more resulting in a faster rescue
