A concern the rider should have when it comes to the safety of the fin is what will happen to it if it is damaged?

All new fins have nearly the same surface finish, however sometimes a fin can become damaged e.g. the wakeboard is dropped on a concrete dock. When this occurs it effects the surface finish. With an aluminum fin it is not that big of a deal. In the worst case scenario the most it is going to do is dent or bend. It is unlikely that a sharp edge will be created. However, with a fiberglass/graphite fin this is not the case. Since fiberglass/graphite fins are made of a composite of glass (or graphite) and epoxy they generally do not dent. Instead they tend to easily chip or break away leaving very sharp ragged edges of glass or graphite. If this happens it could be dangerous to the rider if they continue to use the fin.
