"I have the right to do it therefore I will do so". The queue at the lock, and people giving way to you, and first-come-first-served at anchor, are well established, obvious and crucially see the same behaviours equitably by all involved.At busy times I'd guess north of 50pc of the boats sailing in Chi Harbour don't even have engines. (There are often fishermen anchored or drifting about in the entrance, not sure where they fit in to this.)
You can tag on the emotive language of your choice, but that's the reality of cruising sailing, especially in the South of the UK. When I go out this weekend, everyone behind me will have to wait longer for the lock* several people will certainly have to give way to me sooner or later.* If I go up a deserted creek to watch the wildlife alone another boat can't have it to themselves. Wherever I anchor I'll be spoiling someone else's view with my plastic sailboat and this time of year taking up precious space. What about people who keep their boats on swinging moorings? Literally taking up valuable sailing space year in year out.
* They may be a newbie and that may put them under pressure.
Quite unlike, and entirely irrelevant to, the desire to sail out of a crowded channel when others are motoring.
