Seems to be a common occurrence, so how do you loose a foil? They aren't exactly small.
It can happen when the screws don't hold. I often find that one of the screws on my fins is loose at the end of a session. It's often linked to old or missing o-rings. Using a powerbox or making ground contact does not help, either. The loss can be at a random time afterwards. I once lost a fin 150 km into a session in hip-deep water. Spent 20 minutes trying to find it without success. It's very hard to judge how far you traveled after loosing the fin (or foil).
The Slingshot manual suggests to use a rope (kite string or similar) tied from the top of the mast to the back foot strap. They also specify how many turns the fin screws should be into the foil. So the foil getting loose may be somewhat common. But who reads manuals?
The manual also states that all connections, including screws, should be oiled or greased, and that screws should be wrapped with teflon tape. Good against corrosion, maybe not so good in other respects?
