Prototype production I
simple, inexpensive production of a working prototype that demonstrates the most important technical functions.

A simple prototype that demonstrates the most important functions is generally built in our workshop while the feasibility study is still being made. It is an additional help in the decision-making process about continuation or abandonment of the project.

The rope tightening idea was quickly incorporated in a complete mast foot at the company, so that the main functions could be tested. What was important here was whether the sail tightening principle worked at all in practice. If this had not been the case, the project would have been abandoned at this point.

The functional test with the prototype of the windsurfing mast foot was successful.
