The pics don't worry me at all - I may post some pics sometime, of my boat when I took her over.
However what rings bells with me is that you bought a ferro-cement boat some three years prior to breaking free with exterior damage including a crack that was shipping water. You repaired some months later (perhaps a year later?) by just applying cement from the inside which might stop water ingress but certainly wont't protect the 'ferro' (there are two quite dissimilar materials in any reinforced concrete structure) but still had not slipped her to repair properly some two years later. In my view, unless your reinforcement is SS316, there's a good chance it's pretty much fucked across the crack line. And so, again in my view, I'm thinking their actions are entirely appropriate.
You also agree that it should be repaired to a 'standard' - which means you think that it's currently not up to that same standard.
But hey - I was just expressing my opinion - based entirely on what you wrote - no need to swear at me!
Clearly you know little to nothing about ferro yachts. They don't use stainless reinforcement, unless the builder was an idiot.
My point here is that the yacht is afloat, is not sinking, is not a hazard to shipping and that the incident was trivial. It was also reported to water police within half an hour of breaking free but they took nine hours to respond, by which time the yacht had drifted a kilometre into a wharf, and then it _was_ becoming a problem. The initial order was made by an MSQ officer who assumed that damage he could see was caused by collision with a wharf.
A crack repair of this type is trivial and non-urgent. The yacht isn't going to suddenly disintegrate and become an environmental hazard. If you don't know that, pull your head in.
