Wouldn't believe it if I didn't see it
There's a vigorous discussion concerning this at one of the other sailing forums (SA). Funny to see all the racers give their $0.02 on what happened, often mixing racing rules with their (mis)understanding of the COLREGS.
Hard to tell what happened as the pictures start after the smaller vessel has altered course to starboard. Apparently they were both on parallel courses prior to the collision. It looks like MF is on a broad port reach, the other vessel would've had to harden up quite a bit to end up on a starboard tack. Perhaps the helmsman was trying to get his camera and autotacked? Who knows. In any case, this guy has got quite a story to (not) tell back at the YC.
As for "fleeing" the scene. I'm not sure about this. You'd have to have a serious combination of stupidity and shock to even attempt that. Fleeing in a sailboat? LOL. More likely that he was concerned that a large part of his bow was missing and wanted to get to safety ASAP. I doubt he was worried about exchanging numbers with the MF owner, everyone and their grandmother knows the owner of that big beast. BTW, the smaller vessle, "Stand-By", is not USCG documented and doesn't show up in the database.
