Evans, I don't agree with you that AIS
being on while docked is equivalent to "pissing on the commons" or being a bad apple and having low moral standards. That label, and your definition of what is "the commons" and what is "moral" is your personal one and, to your obvious frustration, not shared by all here. Many of us are full-time cruisers like you. Frankly, your attitude on this reminds me of certain powers that be in FL ...
Some have black box AIS's that are wired to the common nav instruments that may be in use at the time (just taking on fuel
, planning on a chartplotter
, fixing or testing something, etc). So turning them off involves rewiring to a separate switch and remembering to turn it back on. And not all of us sail in areas where a lack of AIS targets would remind us that our units were off.
Many, of course, are simply leaving their electronics
powered because that is just what they do. I often experience situations where public internet access is slowed because people leave their routers on all the time, even when not in use creating IP bottlenecks and hidden node problems. Same issue regarding commons, although admittedly not a navigation
one. But that is life, and I have changed both my gear
and my tactics for this situation and have refrained from pedantic tilting against windmills.
Unless you were using your AIS to move around the docks, the CPA/TCPA filters, properly adjusted, should have taken care of everything.
On our display system, we have the ability to turn off the alarms for slow moving boats outside a reasonable alarm
zone, while allowing alarms from faster boats. We also can have different color icons for those boats - slow/anchored are gray, moving above a selected speed but not a potential danger
are green and those that set off our alarm
criteria are red.
So we don't need our head
buried in a screen
, we simply need a quick glance to see and understand the situation.
We can easily sail (and have many times) through Newport
harbor and have no issues understanding the situational environment
You really do need to either understand your current
unit's filtering capabilities better, get a unit with better filtering capabilities, or adjust your tactics in using the unit.
This "problem" is here and only going to increase. There are valid reasons to have the AIS on, and I agree there are also times of no reason to have it on. But leaving it on for any reason isn't reprehensible or a moral failure of seamanship. Not learning
how, or not willing, to adjust to this newer navigational environment
does bring some questions to mind.
