AIS
« on: June 27, 2008, 06:12:19 AM »
Hello everybody,

There is a discussion about AIS on french forum. We are sorry because so few people vote. If you are interested, please find the link :

http://www.minitransat650.com/simple/index.php?topic=1290.15

The question is :
Would you like to be able to have an AIS system in your mini ?
3 possibilities (the other are bullshit) :
Yes I want AIS (emission / reception)
Yes I want AIS (only reception)
No I don't want this to be a possibilty for minis

Heard that Imoca makes it compulsory.

But the question is:
Is the radar detector not enough ? If you add the transducer to that you are looking good.
What advance does AIS bring ?

My thinking...

I personally sailed with AIS, and for doublehanded races it should not be needed.
Found it only detract you from looking out. And fishing boats do not have them, and they are the biggest danger.

For Solo, the normal set like Sea Me works good enough.

 Fog is scary though. But you have your big radarreflector too. I notice that speed for big ships is going up in fog, do not know why, maybe because all big ships have AIS, and the small ones do not hurt as much when running into them... (anyone has a source by an MRCC or so, in the Channel to ask if this speed thing is true, or is it because  I can see it on AIS now, and they always sailed that fast ? )

final: how more electronics onboard, how more breaks and how more relying you are on your electrical system. Better learn it without.

AIS gets my vote. Sorry, Leo, have to agree to disagree - heavy fog + shipping lanes + night = brown Mustos. Even with a SeaMe or ActivEcho. It's like being locked in a pitch black room with a monster somewhere scrabbling on the tiles. The AIS receiver weighs nothing, draws milliamps and is at least as reliable as a Garmin 152. Another bonus is that if you do loose your mast, you already have your emergency VHF antenna already mounted.

Redundancy = Good.
Single Point of Failure = Bad.

Nick, what's your next race? Hope to see you around the traps sometime soon - but no Ricard for me, OK?

You get
1) Ships Name Helpfull in calling them
2) You get Pos, Bearing and Speed good to know that you may be on colision course in fog
3) You can set alarm at a zone (simmilar to Active echo)

1 and 2 very good in fog and low visabilaty.

In the US all large fishing boats have AIS also now.

Hi Geoff,

yea you it makes sense to get an AIS system.. I have the receiver and the transponder is on order. You cant skip on safety i am afraid to say. it is an extra pair of eyes and ears in the think fog and lets other vessels that may not have seen you visually that you are there.

Not sure what next race is Geoff but will let you know. The Ricard is always a must when in France mate ha ha

Was fun hey ha ha

I am not against other people using it, go ahead, you will be less fast :)

Nono, even if the US class America approves it, that does not have any effect for Europe.
They used Satphones in the US too. And the US never had a race that was a real qualifier.

Anyone knows if AIS is now authorized?

Found a VHF which has AIS screen integrated at Southampton Boat Show, would that be a problem or a way around the rules?

Cheers

New rules will be published in December or so.
And if not allowed, its not a way around it, they will let you rip out the VHF :)

Hi Guys,

Nick had one installed on his P2 at Douarnenez this year just prior to the Mini Fastnet - the scrutineers had no problem with it (or at least he didn't have to rip it out - he started with it).

Whether or not this is "tacit" approval or a knowing blind eye remains to be seen. I'm giving serious consideration to getting one installed.

Cheers

Geoff

I think that any inprovements in safety should be allowed, AIS included. 

One thing I don't understand is how an AIS system could be integrated into a mini without the use of a chartplotter or computer.  (I see above a radio that integrates AIS... first I've heard of that.)  Is there another way to do it?
