That's a shocker, what sort of cartage money has been put down? and did the boat have an insurance cover-note.
I had an uninsured car go missing in transit for 6 days, there was also no paper trail nor reciept apart from my credit card, to say I was worried was an understatement.
I suspect sometimes carriers look after their big paying mates so pull a few games along the way to ensure the bigger dollars don't get missed.
It's not nice but it is business in Australia.
Best of luck hope it will turn up, even if in the carriers good time .
