Importance of DSC

A safety flyer issued today by the MAIB highlights the importance of utilising the DSC function, and its usefulness on VHF radios.
Worth a wee read.

Treated myself to a DSC handheld last November. I am hoping that I will never get to use the red button, but if ever I do need it it will be the best 220 I have ever spent.

I reckon this guy wishes he'd treated himself. It's a long read, but quite interesting...... http://www.nytimes.com/2014/01/05/ma...=fb-share&_r=0

Good artical.

But I can see why some people would fail to use it.

It seems straight forward, but programing the radio is not always easy, getting the MMSI number was not easy. And above all I can well see how people in a difficult situation would want to resort to old fashion methods that they are familliar with.

I was furstrated in getting my MMSI number, Im still reading the instruction book that came with my radio and of course, apart from the VHF course I did, I havent practiced using the RED button.

Oh, and connecting the Radio to the Plotter was not that easy.

I have seen a thread about some DSC red buttons requireing different methods of operation - which is daft. I should be: Open flap, press, hold for x seconds, shout Mayday, abandon ship.

However, its still a good idea to have one. Id just like to spend an hour with someone with the same radio as mine to show me how it all works

If you have the nonce to install a radio then connecting the NMEA wire really shouldn't challenge you, if it does then should you be installing it?

I've bought a 4 second hand DSC radios when I've bought boats and only one of them was wired up, GPS outputting correctly and had an MMSI number, the others were all wired into the GPS but none had MMSI numbers and two of them hadn't set the GPS to output the NMEA.

The reason many haven't programmed their MMSI is because they have not done their VHF course, I know more boaters who've not got a licence than have one and it's common to see small RIBs with VHF's use a mobile phone to call up the lock at the marina.

As I understood it, regardless of radio, if you press and hold the red button it will transmit your distress signal, just not what the distress is.

Odd, I'd be hoping to stay in the ship...

You should never leave the ship, the ship should always leave you. Unless it's on fire

Amazes me that still despite lots of bad outcomes the lack of LJ in comericial single handed fishing is common.

I was taught step up into the liferaft not down (e.g. Don't abandon ship until the last possible moment and it's going under). The exception is fire, and if ANY vessel I am in catches fire the liferaft is going straight over the side and I don't care if the owner is upset that I have deployed their liferaft prematurely.
