1 - had surf racks and board fly off my car doing 50mph. I don't know how, but all I got was a scrape on the fin. Racks stayed attached to the board. it was kind of funny afterwards. 2 - bad backwash one day and shallow water. Took off on a wave and started to go left, last second I turned to go right, wave jacked up and I went straight down. I heard the board snap before I even hit the water.
