Contact your dealer. Replacing that skeg is no big deal. If the uphaul line isn't in place it gets a bit trickier with needing to lead the line back into the guide tube with a skinny piece of wire but the skeg itself is simple.
If there's no dealer then ask for Dinver when you call Pyranha.

If you were close I have spare skegs for Pyranha, P&H & Venture kayaks here but start local first.
