The only problem with that is it assumes that the designated lookout sees the casualty.

IMO, everyone should be a designated lookout. Whoever has eyes on the casualty, keeps eyes (and fingers) on the casualty.

While I have never had a MOB situation, I have lost stuff in the wake; usually, I am the only one who can keep an eye on the item. Pointing it out only leads to a bunch of "Nope, don't see it. Where, again?" ... and I'm the one wearing glasses...

Thats true as well, however, I personally would rather have someone who has done the pb2 course to act as sole lookout, as they know the procedure, lifting them back on the boat etc. But i also realise thats not always possible to have them on the boat, so yes, everyone should have eyes peeled and be told what to do in case this happens.

By the way, our navman has an MOB red button that you can press, which apparently will then give you the exact position of where they fell in, providing of course you hit the button at the exact time they went in!
Has anyone ever made use of this feature, or is it a useless gimick?

That button also doubles as a marker that you can use to mark all sorts of points not just MOB.

Its a good idea but probably only of use to someone who is used to using the GPS and works well under stress.

I used his feature on the PBII course I went on and to be completely honest it was a waste of time do it. I couldn't take my eye off the casualty (a Bucket and buoy) as I was worried I couldn't find the mark again. I think the only place for MOB button is on a Yacht where turning around to recover the MOB would be time consuming.

Thing is, in a rib you can just turn around and get the casualty pretty easy, so you waste time playing with the gizmos. In addition it is not easy to think about line of approach etc if your eyeballing a 5" screen and the water infront.

We did try and use it on the yacht with the bucket and fender, but with a decent tide running, in the 5 minutes it took to get back, the casualty had drifted. If it had been foggy we'd probably of lost 'him.' - The GPS records absolute position, not relative which would be finominal - For this, there is now a really clever gizmo from Raymarine which is like a personal Epirb, that will help you track back to the casualty, not the position they fell in. - A bit beyond our needs, me thinks ...

The thing is. If you use a MOB feature on your RIB or Yacht you are marking an Absolute position. Yes your MOB might have drifted and you might not be able to find your casualty, but if you a very experienced navigator or the rescue services get involved this Co-ordinate will be used as a central point for a search and rescue.

Do GPS's note the time that the MOB button was pushed, I can't remember?

Regarding the MOB function, for me personally I have only thought it would possibly be of use to aid you in giving an initial position to the coastguard. At least gives them a start point for working out drift of a casualty etc if a rescue is needed.

Saves trying to fiddle with buttons to get estiamted position when the MOB has done it for you and shows you the position long enough for you to send on.

Alternatively if you were quick you could send a DSC message.
