Emergency Radio Procedures / How to read and say GPS coordinates

I developed the attached emergency procedures with the idea that family / friends would know what to do if we had an emergency. I made it with an assumption that I was either overboard, medically incapacitated, injured, etc and they would have to know how to work the radio and relay our coordinates to responders.

One thing that struck me is how different GPS devices / apps report coordinates different. Some use degrees/minutes/seconds, while others use decimals or a hybrid. I don't know how often this causes confusion for the USCG or other first responders? At the beginning of each season I have the family practice reading GPS coordinates from each device and learning how to properly communicate them orally depending on how the device displays them. I laminated this on bright yellow card stock and keep it near the helm / radio whenever we are underway.

On the back I show both how to display GPS coordinates on various devices (including the iPhone) and where various emergency equipment is and go over it with the family at the beginning of the season.

Thank god we have not had to use in an actual emergency!!

Two observations? 1.) 15 steps is probably way, way too much for most people to deal with in a real emergency. 2.) Having numeric digits in your boat name seems like it could create some confusion in an emergency call scenario such as this.

You've got far too new and fantastic of a boat to not have a VHF capable of AIS/Distress calling with the press of a single button! :)

As a person who boats in a variety of waters, one advantage of VHS over Rescue 21 is VHS goes out to all Boaters with VHF radios monitoring channel 16.

In an boating emergency, I would want response time over anything else.

But then again, I believe professionals built the Titanic and armatures built the Arc.

Not sure what you're trying to say with regard to VHF versus Rescue 21 but there's obviously some confusion. Maybe I can help clear it up. For those who don't know the term Rescue 21, it's the Coast Guard's advanced command, control, communications and direction finding system developed and deployed throughout the US to located mariners in distress. It is the heart of the Coast Guard rescue operations and saves lives daily. The system has been integral to over 100,000 SAR operations since it's deployment in 2005. If you have a DSC equipped VHF radio, Rescue 21 records your location the moment you key the mic. No system is a replacement for good emergency procedures, but Rescue 21 is one of those behind-the-scenes capabilities that greatly improves accuracy and efficiency when it's needed most.

Guys, in this context, you're actually referring to the functionality of DSC, not AIS.

Equipment that transmits AIS signals is still relatively expensive, but the good news is, that doesn't matter. DSC is what enables the "Distress" function, and DSC radios are CHEAP!

If your VHF isn't DSC-capable, throw it away and get one that is. Then make sure it has either built-in GPS or is attached to a source of GPS position data and program it with an MMSI.

Good tip.

I recently bought a used Garmin MFD, so it was assigned to someone's account. Garmin's policy was simple and fair: they attempt to contact the registered owner. If that person doesn't respond or deny the transfer in a given time window, they release it. Boat US should do the same, but maybe there's too much "government" involved to make something simple/convenient.

I appreciate the feedback from everybody. Incorporating feedback received by @Stee6043 , @Fat Tony , @iBoat Skipper Doug , @RollerCoastr , @gmacd81 and @ttmott I updated the instructions to take into account the DSC distress button feature of my iCom radio. As mentioned previously the MMSI has been re-registered through Boat US with my contact information after the eventual cooperation of the previous owner. Here are the revised instructions:

Side point... On many GPS machines, you can select how you want to display the coordinates. If your machines allow that, you may be able to "sync" them. Would certainly make things a little easier.

Good thread, though. Thanks for starting it. Got me thinking about making up a cheat sheet, as well.

I installed an Icom M400BB just for this reason, including getting the GPS and MMSI#. I wanted 1 button simplicity for the wife.

However, this thread has been very educational in regards to what happens behind the scenes with this radio. Additionally, I hope you don't mind if i lift some of your cheat sheets for my Ops manual!

On a side note, but important to us inland boaters. Does this work on inland lakes? I've been told that the local DNR and water patrols here in GA prefer cell calls. I find that a little suspect, as the cellular 911 has known issues with location that cant be better on the water than on land.

I have been a proponent to dock mates that a VHF is a better way to get immediate help. At least on Lake Lanier I think there is limited use of VHF in general, either due to old equipment, failure to turn it on and monitor, or they are not even installed.

I think I need to investigate this a little more.
