My interpretation of Warren's original post is that he has a set of personal guidelines, ColRegs or not, that means always pay attention and do everything you can to not get into a situation that might lead to a conflict. Act before one needs to consider a situation of right-of-way. I doubt, and Warren can correct me on this, that he is proposing that everyone, in a situation of potential collusion, give-way without organization.
However, I think the points made about the stand-on vessel acting as the stand-on vessel to avoid ambiguity of movement is an excellent point.
As a 10 year old sailing my pram around Clearwater Bay, I never, in 4 years of going wherever I wanted, had a close call. I attribute that to staying clear from an early assessment of the situation combined with an innate belief that when I changed course, I wanted the other captain to have no doubt about what I was doing. I never adjusted to just cross behind another boat, I aimed to be far behind by the time I crossed his wake. At 10, I had no concept of the ColRegs. All I knew was that you passed port to port and powerboats were suppose to giveway to sailboats. I also knew that was great in theory, but it didn't always work that way, so I tried to cross a powerboat's path only after he was past. A pram has no chance against another boat, period. Same with a hobie 18. There is nothing there to protect you in a collision. You won't get a scratch, a hole or a broken mast, you'll lose a boat and likely a life.
In the mid 80's, early gps navigation, a sextant was still necessary and more accurate, you plotted your course and sailed your heading and tried not to deviate until the channel you were aiming for was in sight.
I was sailing with my father from Ireland to Portugal when the radar showed a strong signal, about ten miles out, on an interceptor course . It was night, of course. We watched the signal and spotted the nav lights. At 5 miles, still on an intercept course.
My father tried three times to hail the ship, describing ourselves as the sailing vessel, 'Absolute'. It was a large freighter out of Italy. This was open ocean, no channels, no restriction to navigation. When the captain finally responded to a request to change his heading, he announced on the radio, "OK, I change course 3 degrees to starboard, NOW!" Almost like he was saying, "Synchronize watches, NOW!"
I don't remember what tack we were on and I don't remember If it was 3 degrees or 4 degrees or 5 degrees. I'm not even sure it was starboard, but the point is, it seemed like a small change, he was maybe 1/2 mile out by the time all this finally happened. The substantive alteration of course in order to make it clear what your intent was, includes the radio. The captain made his intent clear without making more than a few degrees of alteration to his course.
Now I think it's kind of silly to ask the captain of a 500' plus freighter to alter course for a 50' sailboat, but that wasn't my call. We didn't collide, so that was good.
