Friday before last Claverton and I were having a gentle sail on Pittwater on MB. Heading north off the Basin a large RHIB coming from the north manoeuvred around a slower vessel and was on a collision course with MB. Kids on his bow were watching me as he closed at 30kts+. The driver was looking behind him as he closed to 50 or metres with me screaming and waving at him. He continued to close until he looked around and swerved away, maybe 30-40 metres away at very high speed.
I was shaking minutes later. There was nothing we could do, he was just too fast.
