Took out some old and new friends on Sunday for a very special day on the SF bay. We departed about 10:30 and from a distance we could see the Berkeley Kite Festival in the fog. Tacked out towards the City and the Louis Vuittan Cup Races. New Zealand was dominating Italy once more. Winds were in the 20's so we had a bit of jib out for a nice easy sail. As we reached the finish line, NZ comes roaring through. Nice view of these spectacular vessels. Then we head to McCovey Cove for lunch. We anchor and are eating lunch when one of the large brunch cruisers comes through the anchorage. He turns and promptly hits our bow and bends up our bow roller very nicely. I am a bit stunned and contact him on the VHF. The captain says to call him on Monday and he will take care of it. This will be a big hassle I am sure. We did not let this ruin our day and it could have been much worse. Had a great sail home in high winds and I look forward to the next adventure.
