Re: Please turn your AIS off when docked/moored/anchored

Re: Please turn your AIS off when docked/moored/anchored

One thing I personally would like to see on 'yachting alarms' is rather than just a generic buzzer, the AIS alarm says "AIS, AIS, AIS" and the engine overheat alarm says "overheat, overheat,...

Re: Please turn your AIS off when docked/moored/anchored

^^

With what I called the 'special alarms', the trick is obviously to set them so as to balance false positives against false negatives. From your post, I would (most humbly) suggest you have...

Re: Please turn your AIS off when docked/moored/anchored

Jut a comment on 'alarms'. I understand a few of you don't have much use for them. However, it's pretty well documented that they add safety. Humans lose focus and their attention wanders. This can...

Re: Please turn your AIS off when docked/moored/anchored

Negative, I can and do get safety and nav messages on the vesper. It sounds like the difference to class A is that I cannot send any text messages.

Re: Please turn your AIS off when docked/moored/anchored

One would suppose wrongly :)

I have a wireless remote for the autopilot. I can change course, or even 'directly hand steer' from anywhere.

I would most often be near the front end of the...

Re: Please turn your AIS off when docked/moored/anchored

Thanks, interesting. I had no idea they could control it in all those ways. I now vaguely remember reading the notice, that Nigel liked to above, but at the time I thought it was a class A only...

Re: Please turn your AIS off when docked/moored/anchored

Just FYI, the paper that Dave linked to a ways above, calculated that 182 class A ships with generate a 20% slot saturation (there are a lot of assumptions which they detail in the paper). I think...

Re: Please turn your AIS off when docked/moored/anchored

I worked on a project for Verizon two winters ago on 'machine to machine' auto tracking and collision avoidance. I was the M&A guy on the team, but I listened to and read all the technical discussion...

Re: Please turn your AIS off when docked/moored/anchored

Thanks! Interesting. It would be interesting to see this at 1pm on a SF Saturday, and in the greater NYC area?

Re: Please turn your AIS off when docked/moored/anchored

No I do and DID not.

I am perfectly happy with people operating differently than I do. I am perfectly with Jedi running a Class A unit. I am perfectly happy if Mark does not use alarms much and...

Re: Please turn your AIS off when docked/moored/anchored

Mark, in fairness, I find your post a bit frustrating.

Do you really think I should have set one low speed filter when approaching Newport and then removed it when I was by?

I don't know...

Re: Please turn your AIS off when docked/moored/anchored

The way AIS class B is structured today, both technically (CSTDMA with 'noise sensing') and in the commonly available filtering/displays, "unnecessary signals" (We can discuss what that means later)...

Re: Please turn your AIS off when docked/moored/anchored

Re: Please turn your AIS off when docked/moored/anchored

No, my point was that EVEN IF you accept this dismal view of humanity, you and I should not accept it as an excuse to act badly. We should still 'do the right thing' even if the entire rest of the...

Re: Please turn your AIS off when docked/moored/anchored

^^

The filters on the Vesper can be adjusted - you can set all of "target range', 'target speed', 'target cpa', 'target tcpa', 'guard alarm range', 'your speed'. You can set these however you...
