Hello!

I've recently brought an old Mistral Maui board to learn windsurfing.
But my sail seems to be bad, because the bunting can not be bent enough and half of the bending bars (I don't know how to call it in English) are missing. Plus the boom is oldstyle too without quick fixer to the mast.

My quiestion is that can I buy any kind of new complet rig for this? I mean does the new ones good for this surf? Can I pull them (sail and boom) to this old mast?

I'm totally new in this, so thanks for any answer.
