The stupid sharp tips on many SUP foils always bug me.
Why the heck can't we design a "safety tip" out of some firm moulded plastic, to dull the knife-like edges on these wings?

This picture of colas is a wake-up call for any would be foiler or foil company that doesn't want to end up on the wrong end of a lawsuit.

If high Speed aircraft can have wingtip gas tanks....
Why can't SUP foils have similar (shorter) wingtip protectors?
