"The name of the 40ft boat is "Stand By.
A few minutes before this photo sequence, the Falcon had turned to port, to give the right of way to the smaller yacht, which was to leeward on the starboard tack. The "Stand By" was originally on a roughly reciprocal course to that of the Falcon. Prior to the photos shown here, "Stand By" was bearing away, and the two yachts were on safe courses to pass roughly with a distance of 200 feet separation. After the "Stand By" had sailed past the Falcon's bow, the smaller vessel suddenly rounded up, possibly to tack in order to follow the Falcon, when she lost control, and with her main sheeted hard in, the smaller boat was unable to bear away to avoid a collision.
A San Francisco Bay Pilot, was on the Falcon's bridge overseeing the Falcon's course at all times. The pilot is also an experienced sailor and sail boat owner. Because of the Falcon's tonnage, a licenced pilot is required whenever the yacht is underway, approaching, or inside the Bay.
The "Stand By" did not stop after the collision. The Falcon furled her sails and pursued the 40 footer, under power, in order to determine her name and registration number. The pilot radioed the U.S. Coast Guard who intercepted the "Stand By" and boarded her.
The accident was caused by "Stand By"'s sudden change of course, which was much to quick to permit the Falcon to respond. The Falcon sustained damage to hull, capping rail, superstructure and main lower topsail, but fortunately there were no injuries to persons aboard either vessel.
