1909  The schooner Roderick Dhu was discovered in distress on the bar by a Life-Saving Service patrol from the Point Bonita, California station. The schooner had been in tow by a tug, but parted hawsers when 5-1/2 miles SW of a LSS station.  She hoisted a signal, and the keeper reported her condition to the Merchant’s Exchange.  A tug was sent out and the schooner was towed to sea.  The next day she was towed into port, leaking badly, and convoyed by the USRC McCulloch.
