I feel your pain.I was on a weekend away with 8 mates when I copped a nasty fin chop last month. A late take off resulted in a big nose dive, I wasn't sure where my board was so I wrapped my arms over my head just in time for the board to come back at me fins first. Felt my fin go straight into my arm & then my head. I got out of the water pretty quick to find my arm sliced open & my head bleeding.
We were on a deserted beach about 1 hour from a hostpital on unsealed roads.
Ended up with 9 stitches in the arm & 4 in the head. Pretty lucky that I covered my head or it could have been alot worse.
I couple of Cooper pale helped ease my pain that night too.
