First hand knowledge of the inconsistencies of C&RT. I had interest in canal off side land for sale. I contacted C&RT asking for advice on the likelihood of getting mooring permission. They replied citing the on line mooring reduction policy which when applied to this land failed on a couple of points meaning no likelihood of getting the ok to moor boats there. The land was sold and within weeks a boat appeared then another..... now they are building a marina there. Good luck to them, not sure what route they used. So there can be inconsistencies in C&RT’s approach. My advice would be as there are boats there already double check C&RT know about them and ensure you have it in writing the mooring right transfer will be honoured by C&RT ( no reason why it shouldn’t ) as to the other parts of the question, more a planning issue with the council. Good luck, most peoples dream.
