Re: Give AIS a rest

Digging deep into history, I recall how difficult it once was to determine whether a crossing tanker was going to be a collision hazard (certainly no AIS at the time). Their size made them appear closer than they were and moving more slowly than they were. More often than not, they were long, long, long gone, before I was ever close to their path.

I will bet there are some recreational sailors that have bitched that the tanker didn't give way and moved themselves, while the tanker knew all along there was no risk. So, what CPA distance constitutes a need for anyone to alter course?

In the end, if you're not at risk of swapping paint, no one needs to give way.
