The most important part of boating for me (especially on the canal) is that I never have a schedule to keep to, can trundle along as slowly as I like (without causing an obstruction to those who have to hurry) and can, as I always do, slow down when passing any moored boats, occupied or otherwise.
I maintain steerage way at all times, I am, after all, supposed to be fully in control of the boat (though even steerage way does not always guarantee that ) so I will be moving faster should the weather conditions dictate.
Others may not have the same attitude - that is their choice and I only object if they spill my coffee (or, far worse, my alcohol)
The former may cause me to lower a condemnatory eyebrow but the latter can and does cause me to raise my voice.
You wouldn't like me when I'm angry
