Already on my list dude. My plan is to moor up super quick & then go birdwatching until it's nearly dark. If i'm not there to ask to move...
Then I'll show the cottage owners what lovely people boaters are by being all happy & cheerful, complimenting them on the garden or whatever. I may even offer them my ashes* for their roses. I shall endevour to make them feel good about themselves some way and then hopefully they will associate this feeling with the next boat to come by who will hopefully be as pleasant & considerate.
it's the only way if you think about the long term...
* edited to say: the ones from my fire, I'm not thinking that long term!
