Buying bits and trying stuff.
The latest purchase is a tall mast for the foil.

All masts are available as separate accessories without screws, available separately, to accommodate different skill levels and sports.
Currently I am using a 70 cm foil mast and the XLarge wing for surfing and the 85 cm mast and the Large (WS1) wing for windfoiling.
