Chapter 10 I assume applies to most commercial vessels. The commercial vessels on the Delaware travel at a speed that is probably appropriate for conditions, but the wake just outside the shipping lanes can be dramatic, probably also influenced by change in water depth and shore line condition.
With a few minutes to prepare if I am keeping a watch as I should, turning the boat to receive the wake at about 45deg off the bow is good enough. If i am in the shipping lane and too close to the commercial traffic it is my fault not the fault of the tug or freighter.
Pleasure power boat traffic, if I keep an appropriate watch requires the same adjustment of bow to wake front. Most power boater will slow down but as Otter observed coming off plane can produce a larger wake.
In no wake zones or within a marina big wakes are only produced by big A-holes.
I have experienced many unpleasant wakes but not anything I would call dangerous.
