I fall into the group that hate unnecessary DSC alerts, and began to doubt it's value.

Until today.

It was forecast F3-4, but turned out to be the upper end of a F5, which made conditions a bit bouncey coming back from the IOW to Chichester Harbour.

The DSC alarm went off, and hitting the "plot position" button put it less than a mile or so away from my current position. A follow up call came on Ch16, but the lady was obviously v.stressed, and couldn't give her position, or vessel name/type, only that the skipper had gone overboard, and that they were somewhere out of Chichester Harbour. There were several vessels in the area, but it wasn't at all obvious which was the one in distress until I was only a few hundred yards off.

By the time I turned up, the yacht had drifted a bit from the original position, and the skipper was in the water hanging on to the stern, not looking too happy, but still hanging in there. Another sailing yacht was on scene, but they couldn't get close because of the choppy sea. I might have tried to deploy the tender, but it was wavey, and I could see Hayling Rescue (aka "Frank") coming thundering through the chop, so shouting encouragement and relaying a few msgs to Solent Coastguard seemed like the right thing to do.

Within a couple of minutes, Frank and a lifeboatman had the skipper on board (they had to put a man in the water to get him out), and the yacht under tow: all in a days work for them. Then two lifeboats turned up. One asked if I was okay!

Anyway, the point is this:
There is no way that the lady on the radio could have issued an accurate position report, but she managed to hit the red button, and the DSC alert did it for her. In an ideal world, she would be fully trained in distress procedures etc.

In the real world, I think that a skipper was saved by DSC today.

A very interesting post, a life in danger in the busy Solent on a sunny Saturday. Goes to show how technology does sometimes work wonders....

I have trained my 6 year old daughter how and when to use the DSC button.... if that day ever came I sincerely hope boats would come from every direction to help.
 
...agreed.... and compare that to the mayday I heard yesterday afternoon (26th) - same area roughly as your example, for a boat I think called Jessica - Solent coatsguard had to ask two or three times for the name of the boat - lots of wind over microphone made it difficult for them to hear correctly - then they had to try and understand where the boat was - same issue with wind etc. All ended happily (HI Lifeboat got to them) but a very different picture to the DSC enabled rescue....
 
Problem with DSC is it was technically obsolete before it was even released in products. Being transmitted by ancient anologue technology, and with very limited functionality. I agree though that having a simple RED alert button for any inexperienced crew member to hit in an emergency is a good safety option. BUT how many untrained crew know to keep it pressed the full FIVE SECONDS?

A digital based system where both text and voice would have been a better solution as transmissions would only take micro seconds instead of real time, freeing up busy VHF capacity. Civil aviation is going this way for safety and efficiency on aviation VHF. It will avoid crews transmitting over each other, and having to record and remember audible flight instructions, minimising confusion and errors, due to logged send and received text messages between ATC and aircraft. It does seem that a marine VHF should also be able to act as an AIS transciever given it's already hooked up to a GPS source for DSC lat/long. ICOM have done this with some limitations on their nice 505 set.

Yes a good result, but so often a DSC call goes out and people just turn off the radio or hit the stop button because the DSC sounds so often and is usually a false alarm! folks just get fed up with it! My wife would be the same though, she could hit the distress button but would not be able to give a position!
