I've just checked my own boat insurance details, and it states that they cover our vessal for (among other things), acts of accidental damage, acts of vandalism and acts of deliberate dame (not caused by you).
For those poor soles whose boats have been damaged, should (if they are insured) should be able to claim off their own insurance companies.
Having worked in the insurance industry (albeit motor insurance), I would expect that the damaged boats insurance company will attempt to get reimburements from the drunkan lady and her insurance company (presuming she was insured, which given her attitude to the rules of the waterways, may well not be the case).
As to her criminal liabilities, well - lets hope we hear molre of what happens to her.
