Having portrayed yourself as something of an expert in things canals and narrowboats, apparently on the basis of YouTube "experts", and got pretty rude to those trying to help you understand, you now expect us to take your claims at face value. Sorry, but the world does not work like that, especially when you can't seem to help yourself nitpicking and throwing insults at people, as shown by your comment in the final paragraph above.
You have been asked for proof over your claim that you have received emails from forum members supporting your conduct, but so far have failed to provide any. That, in itself, calls the veracity of your various claims into question, let alone your early assertion that narrowboats are built with stud wall bulkheads. Some, may be, and many probably have hidden cavities in which to run services, but not on the scale you were asserting.
You have been asked for photos of your boat and some of the problems etc. that you have had to deal with. Again, no response from you. This again calls your veracity into question.
Now you apparently display your accrued warning points, from an unknown source as a badge of honour, suggests you have problems, with your apaprent lack of veracity being a pretty minor one.
Sailing experince is not directly relatable to inland waterways, esecially canals, although resolving engien and domestic system problems probably is, but you don't seem to use your such experence to help others here, I wonder why that is.
