Gath helmets weigh very little, less than wet hair.
That's the kind of specious argument you get from lonely men with way too much time on their hands.
I've worn one pretty much since I started short-boiarding in 1994, and have had a few random cracks about the head, often in light wind, so I would not use 15kt as a cut-off. Always grateful to have it on.
As a bonus, you get very good sun protection for much of your face and ears etc, though nose and back of neck miss out a bit.

I have toyed with the idea of wearing a helmet but I am told that if you have a long neck (which I have) the added weight of helmet plus head causes increased likelihood of whiplash injury which may outweigh the positives of wearing the helmet.
The last 2 times I have received head injuries whilst sailing it was my nose and my chin, which would be unprotected by a helmet anyway.
