That is correct. That's the first part of the answer. There is no compulsion by law for those operators to have insurance.
The second part that I think I need to mention, though, and perhaps it wasn't too clear, is that leaving insurance aside, it is not as if the operator of such an adventure tourism vessel or series of vessels cannot be made liable in law to compensate the victims of a personal injury or whatever. Of course they could, and they would be at law like any other claimant. They would not have the passenger regime--we've clarified that. They're not in part 4, but that doesn't preclude in any way, shape or form lawsuits being taken against the operator to recover for their damages.
