Maybe a slightly different perspective with a couple of examples.
As we all should know, we are responsible for our wake and any damage or worse yet injuries it may cause. However, practically this may be difficult to actually prove. There is also something called "common courtesy" which I unfortunately find is too often lacking today what with alot of people being so centred on themselves.
There are extremes of both ends of this discussion, including the "wake draconians".
I moor at the Nanaimo Port Authority on a short dock (side tie). There is a reasonably sized marina and a busy fuel dock near me. If someone leaves the area (which is designated as "no wake") too fast (meaning generating a relatively large wake) at just the wrong angle, I receive broadside waves that actually pass under the dock I am tied to and violently rocks items off of my counters. One time, my mechanic had just finished (and had left the engine room) and he saw the wake coming and grabbed some items to save breakage while steadying himself from falling. If he had been down in the ER, he could easily have been injured!! This is not a one time event, but does not happen too often, mostly because the angle of the wake has to be "just right" to cause this much of a problem for my boat.
Another situation that I witnessed was while at the dock at Refuge Cove. This is a very busy fuel dock with provisioning store in Desolation Sound. Often boats come in way, way, too fast and don't realize that their wake follows them. The time I am referencing, it caused boats to rock so hard, that one woman (on a relatively large boat) was literally thrown around her galley. Luckily, she was not seriously injured.
Some of the "wake draconians" may have experienced things similar to what I described, but may be guilty of "over reacting" also.
I cannot be responsible for the actions (or inactions) of others. However, I can be considerate and try to think and act safety.
Around marinas, fuel docks, no wake zones, I slow down and observe what my wake is doing to others and try to adjust accordingly. In narrow channels I do not pass other boats (if a very long channel I would contact on VHF and ask them to slow so I could overtake with less of a wake). I also try to give canoes and kayakers a wide berth so they at least have a chance to take the wake to best advantage, and in some cases, I slow down for them as well.
I am not trying to preach here, just saying we can all be "more aware" of what our passage does and when appropriate try to be courteous to others.
Even for those who are already acting responsibly, look behind you and see if "what you think is happening" is "actually what is happening".
Just some thoughts.
