Never had an issue myself or read of one in here but it would pay to be switched on. I launched about 2-30 am thurs, was the only car parked at WB and when i was at the rigging bays a white tray top ute rocked up, could've been one of the workers of the job going on there, i didn't know but i was not leaving the boat alone till the ute left.Ohh yeah, buy a trailer coupling lock too.
