Forgot Weight Belt, Not done zip up properly, had cylinder fall out of BC...Been there done that.
My best was whilst returning home on a bumby Rhib ride. I was sat at the front sitting on the sponson getting covered with water. Eventually fed up with a mouth full of sea water I leaned over the side of the fast moving boat to spit out the water. I did this and managed to get the poor sod sitting to my left right in the face.
Whoops!
