That makes even less sense. If the boat was sold on 12 April for cash, by hilaleigh432, and disappeared later that month, then it wasn't the OP's boat when it disappeared. So none of this is their business at all, it would be up the purchaser to pursue it, if it vanished at all. Presumably the OP was happy with the cash; the only reason CRT might dispute repaying the licence would be lack of registration from the purchaser, but they did repay so accept it had been sold and gone off piste, so to speak.
Also odd, I think this is the first mention in a long thread that the boat had been sold before vanishing. But how can a boat that you've sold, and pocketed the cash, be referred to throughout as "my boat"?
It's really not a stolen boat story at all. Some has bought it legitimately, paid cash, didn't want to licence it, sailed it off and repainted it somewhere. They'll be living happily in it on the towpath somewhere with no name or number and avoiding spotters.
