It looks like he wasn't in control of his vessel at all. The jib is furled, but the main is in a pile on the boat. I'm sure that when his buddies dropped the dime to the CG, they were not there in a matter of minutes. The main should have at a minimum been tied down. The CG comes up, some hours later, see sails flogging, lines in the water, etc. The call by the captain would have been a no brainer.
