So, here a small suggestion.
The class control should shift to the following when the number exeedes 10.

Designers who have for free provided a design of a F12 for others and have at least one cat built out of this design.

Builders who have built at least one boat ready to sail.

Owners of a redy to sail F12 cat

Each person has one wote.

When the number exeedes 49 this group should within themselves for a counsil to take control of the class.
