Hi all, after a bit of help and if I can seek some opinions and/or thoughts.

Context: 40cm Carbon fin (sorry, don't know the brand) off a 2000-2003 Mistral Panam Raceboard, Rig NP RSX 9.5, Centreboard Mistral Panam Carbon.

Issue: Fin took an accidental drop when the board was being worked on today and added to the other chips and stress fractures (hopefully the pictures are clear enough).

Questions:
1. Can the fin be repaired? and any suggestions for a repairer in Sydney? (the centreboard also has a chip on the trailing edge that I should get repaired at he same time, if possible).

If not repairable, then for replacement:
2. Is the sailors weight critical to the fin size?
3. What size fin would be optimal with this board?
4. Is a carbon fin that superior to a G10 glass fin, as not to consider a glass fin? and what brands and sizes?
5. Do Raceboarders' have more than one fin, say a light wind one and a strong wind one? what size do they/you use?

Thanks heaps in advance for the help.
