I don't usually on normal sailing and gibes, perhaps once a year.
In this case and other occurrences, it happens whilst trying stuff (in this one, aggressive board 360 through a gibe) and I seem to concentrate on other matters such as foot placement. Happens also on some flakas.
Still, it happens. The scar is HUGE and colourful - and well deserved.
Hence my time to write in this forum
