The events leading up to the beginning of the video would certainly give us a better idea of what could have been done to avoid the loss of the boat. All we get to see is a vessel out of control for approximately 3 minutes in rough seas, onshore wind that was estimated at 30+ knots, mainsail out of track and out of control, and a jib that is partially wrapped with no control, with a lee shore (pier) approaching fast. Without the main to power them to weather , further offshore , they were doomed. With only the jib partially available causing a lee helm, combined with stiff onshore winds and seas pushing them to shore, the outcome was inevitable. As King stated, even if they had jibed earlier, they would have landed on the beach on the other side of the pier. That would have been safer than crashing into the pier. The only way out, in my opinion, was to drop anchor immediately and to sort things out with the sails and rigging or possibly calling for help while anchored. In the 3 minutes that we saw, I don't think there was enough time for the harbor patrol to get on scene and get a line secured. Real scary stuff; truly amazing that everyone escaped unharmed. Best decision that they made was to have pfd's on. As others mentioned, that's a difficult harbor approach under the given conditions without full sails or lots of horsepower.
