You're right. I put up a straw man that couldn't possibly happen. After all, the Internet is never used for illicit activity.

Just think about it. When your VHF picks up a DSC call, what happens? Ours will whine like crazy and I have hell of a time to mute it (say if my crew are asleep).

A DSC MOB device works exactly along the same lines: a distress DSC call is put up on air: all DSC VHFs should/will light up red, pick up the data and store it for your reference: call nature, position, caller id, etc. Many will let you navigate to the caller with one press of a button (ours does).

And your plotter will display the MOB. Off course, only if you have it wired with your radio, which is not what all boat owners do.

I have seen a test of DSC AIS MOB device and it lit up all alarms (DSC on the radio, DSC on the plotter, AIS on the AIS unit). Maybe this technology is not allowed in the US. I know they have their own regulatory bodies out there.

Re: AIS and cruising

I am pretty sure I lost my privacy back when my bank, my stores, and most likely the IRS, was hacked. Personally I don't care if they know everything about me including my underwear size if we can hail each other in the fog and confirm who we are and which way we are turning. (I think it's 34) But then I don't have a very expensive TV at home to steal.

Re: AIS and cruising

Looking at Marintraffic I noticed something quite odd. Go and look for yourself what most ships around the Horn of Arfica have set as destination port in their AIS transponders...
