AIS Registration, MMSI Number

It's not Able Seaman, I'm an engineer. What does your MMC list for "Capacity" for which you are qualified to work aboard as crew?

I think you are mistaken.
This is a normal conspiracy theory (so loved by Americans).

Read up on all the other goodies DSC does like actively hailing another DSC VHF MMSI on the reserved DSC hailing channel and shifting their VHF to the working channel you preselected. There is a BUNCH of convenience neat stuff DSC does other than distress.

You went through the trouble to get the MMSI, may as well use it to its max. :-)

This is the point of getting the MMSI number....
And, contrary to your comment on the AIS being filteres, I have been routinely contacted by name of our boat by merchant vessels. They see our AIS and see our yacht's name on their screens (if not asleep...)

I have to go to work now for the next 4 to 6 months, 24/7 except for brief stops in Spain, Italy, Greece, Djibouti, UAE & Bahrain. Working as an Electronics Technician aboard ship maintaining, supporting and repairing the ship's electronic systems for a living.

I urge you to read:

http://www.panbo.com/archives/2010/1...dr_norris.html

I know this will stain some fervently held world views but, so did overcoming the notion the earth was flat over several centuries.

I also ask that the Internet be scoured for colregs, CRF or regulatory policy letters bestowing legal standing in admiralty courts foreign or domestic to class B AIS. Granted Singapore and Thailand do stand as exceptions so their may be others I am as yet unaware of and can benefit by learn about.

I also wonder how many of the ardent class B devotees out there have enabled the DSC in their VHF with the MMSI they secured for their AIS? Additionally, have connected the VHF to receive GPS data or are really familiar with all the functionality their DSC VHF offers?

I did all of that.
I am fully versed in all DSC functions of the radio.
Never actually initiated a dsc call on the VHF though. I did respond to DSC calls.

Makes an awful racket if you don't...

Obviously I have done that. Probably not a good idea to assume that recreational cruisers are not capable to know the simple details of things like this. I also read some of the blather over on GCaptain. I believe the vast majority of US ships are captained by folks that actually know COLREGS and adhere to them. Just because someone knows or has heard of a bloviating GCaptain user with AIS B filtered and no DSC watch does not mean that is the norm, at least in the US and Europe.

The biggest benefit IMO of AIS is to be able see other vessels. It's not only the big ships I worry about but smaller recreational craft that can improve their watch keeping by having AIS both transmit and receive. Dissing AIS B is doing a disservice to the cruising community, again IMO.

For that all you need is a receiver. You silence the transmitter.

How many days of seatime do you have documented in Sea Service Letters to be so stridently informed with such profound certitude?

As best I can understand SV Enough's position on this based on the other thread where this was debated at length, He thinks that only boats required to carry AIS should carry it, and no others. Since the carriage requirements are only for Class A, that obviates the need for Class B. And since he thinks every vessel carrying Class A filters Class B, what use is it anyway. BTW, if that's not what you think, please correct me, as I'm not totally sure what you are arguing should happen.

I just have one simple question that was never answered/fulfilled in the other thread. We have lots of licensed deck officers here, myself included. I'm talking about the person in command of the vessel, not a tech or some other support staff, but the person who has command of the vessel. I'd like to hear directly from those who turn off Class B targets on thier ECDIS, ECS, Radar, or whatever, when, and why. All the articles are speculation, and all the deck officers who have spoken up say it would be foolish to filter out Class B targets. Filtering stationary target, and targets beyond a certain distance - yes, that makes sense. So I'd like to hear from someone first hand. Until that happens, I really wish all the speculators would just STFU.

Enough is out of control and wrong, don't feed him more. Use class B transponders. i have had both class A and class B and the results out at sea are equal. In port it's different; I also disable alarms in port sometimes. I have 268 targets here.

[s/v Jedi]

Busy enough for y'all? :-)

Do most boaters who spend a month or more in the Bahamas each winter get the FCC mmsi registration, or do they just go with the BoatUS version?

It's common that the less skilled/knowledgeable/experienced a person is, the more they fixate on formal written credentials.

You are once again proving the point.

I'll just put my 2cents in on this discussion...we don't rely on the AIS so that ships can "see" us. Our job is to stay out of their way. But, at night, when the lights of distant ships start playing with our imagination, it is an invaluable resource to check our AIS targets and see their bearing, their SOG, and their size. The AIS offers peace of mind in that respect for us.
