Also the Shroppie "winding holes" are not subject to EOG charges. There is case law to the contrary of CRTs ability to charge for EOG moorings (on some canals) as the right to moor boats was included in the canal enabling acts, these still stand with the exception of the public right of navigation which was subsequently Abolished.
BW vs Yardley Gobion is a very interesting case, part of the BW argument was Infact that the right to moor boats (against the bank / create a layby) was included in the enabling act.
The case would be a interesting read, good look finding it.
