the keels. Some of that later video showed no rudders remaining and I could only see one saildrive lower unit. If the lower unit(s) got torn off or severely disrupted then it's likely there was water ingress into the hulls as well. The keels can be replaced without strong technological skills, rudder less so and saildrives even less. I don't envy them whatsoever. It's certainly what I'd call a "Bad Day".
