I for one DID read your posts, and I have been mostly polite and courteous to you here, but I'm wondering if you, yourself, have read any of the IMO resolutions about AIS
Because, if all you desire is for the IMO to say AIS is a "collision avoidance" tool, then PLEASE read the IMO's own resolutions, adopted and approved 15 years ago!!!!
And, your desire will be met and the arguments your propagated here in this thread will be moot, as the IMO DID actually approve/adopt AIS as a "collision avoidance" system / tool, back more than 15 years ago!!!
And, here is just some of what they adopted when working out the rules and AIS "performance standards", note THEIR use of the words collision avoidance, in regards to AIS!!!!
I highlighted them in red, for you....

RECOMMENDATION ON PERFORMANCE STANDARDS FOR AN UNIVERSAL
SHIPBORNE AUTOMATIC IDENTIFICATION SYSTEM(AIS)
1.1 These performance standards specify the requirements for the universal AIS.
1.2 The AIS should improve the safety of navigation by assisting in the efficient navigation of ships,
protection of the enviroment, and operation of Vessel Traffic Services (VTS), by satisfying the following
.1 in a ship-to-ship mode for collision avoidance;
.2 as a means for littoral States to obtain information about a ship and its cargo; and
.3 as a VTS tool, i.e. ship-to-shore (traffic management).
This is a direct quote from the IMO....
IMO RESOLUTION MSC.74(69)
(adopted on 12 May 1998)
ADOPTION OF NEW AND AMENDED PERFORMANCE STANDARDS
Poweraboat, PLEASE take note of my use of red font on the IMO's use of the words "collision avoidance"....and also take note of the date that these new performance standards were adopted 12 May 1998...15 years ago!!!
Also, please take note that "collision avoidance
" was the #1 requirement of the system, again according to the IMO....
In addition to this IMO document (which, BTW, I found in couple seconds at the USCG site) http://www.navcen.uscg.gov/pdf/marco...69-22a1-12.pdf
there are many more IMO documents that state the primary purpose / design aspect of the AIS system is, in fact, collision avoidance
Now, I'm NOT saying that everybody needs to have AIS on-board or they'll die...
(and I am VERY well aware of the plethora of vessels / hazards out there that do NOT have any AIS signals...)
Oh, and as for the ColReg issues...that was already written about and shown NOT to support your "myth"....
Heck, even USCG Rule
#5 debunks your "myth"....
USCG Rule 5 - Lookout
Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.
Please do not twist my words!!!

I was asking/pondering
whether some of the professional mariner's survey

there is a much greater percentage of commercial shipping
with ECDIS on-board which ARE displaying AIS!!!
Poweraboat, your premise has been proven incorrect by information from the exact, specific source that you desired...the IMO....
And, further, you seem to be grasping at straws (trying to twist my words) in order to stick with the myth/misinformation that you've formed into your own little story...
An intelligent and thoughtful sailor would say "Thank You" for the education, and apologize to me for twisting my words???
And, now that I've educated you in the facts, that the IMO DOES in fact classify AIS as a "collision avoidance" system, I expect that you will promptly apologize to Ben!!!
We are all waiting....
Finally, poweraboat, from one sailor to another....(opps, you're a powerboater....)
Well then, from one human being to another, if you persist in propagating lies and misinformation to the sailing/cruising public, you're liable to butt-up against some that are not as polite and courteous as I am...
And, someday soon, you'll even find postings from me that will start off with something like this: "Not sure what bar stool you've propped yourself up on today
...but what a load of crap!!!"
So, use caution when typing, as I think you've learned here, you are NOT the smartest guy on the planet...not even close to the smartest on Cruiser's Forum...
