At the end of the thread of “Post your hull Pictures” is a photo of a leg gash from a fin encounter.
Many fin configurations pose a hazard to the surfer.
I admit to making some that will leave their mark if the rider isn’t careful.
There
are some simple rules, one of which is that if you do wipe out don’t
come up out of the water quickly because your board may be directly
overhead.
There a few others that I’ll let the experienced surfers here post for the safety of all.
