And people do not draft off of their escort boats, or use them to block chop. If they do then the observer is supposed to say something. Can't recall the exact distance, but swimmers have to be off to the side of their boats. What we have found that swimming too close to the side ends up being a huge disadvantage. The cross chop that comes off the boat makes a washing machine for the swimmer, so we always keep our guy well off to the side and a bit in front of the boat..I'm sure you have a lot more real-world experience in this than I do. But over at places like marathonswimming.org you'll find discussions from experienced channel swimmers about best using the boat to block chop and wind.
It's also my understanding that in the English Channel itself, swimmers are required to stay within 5 meters of the boat at all times, simply because it's such a busy shipping lane. Like you said though, each area has its own rules.
Keeping the swimmer to front and off to side of the boat seems a lot less assisted to me.
We'd love to hear more about your Sea of Cortez swim!
