From the every beginning of the star class the class rules have been changed and adapted to the latest development in design and equipment. The most obvious changes occurred in the sail plan and rig. But even when the principal dimensions had not been changed, innovations, sometimes examples for many other classes or even the whole sail boat racing community, were introduced and became common. A famous example is the so called “German Rig” or “Flexible Rig”.

It is amazing to see how quick changes have been implemented, not only for new boats launched but also the the large existing fleet. The Star Class Organisation (I.S.C.Y.R.A.) on the one hand side was quite restrictive concerning changes of the plans to protect the owners of the existing fleet, keeping the whole fleet for many years competitive and by this the value of the existing stars. Only very few ideas of the many proposals found their way into the class development and rules. On the other hand, if a decision had been made to update the star and her rules, the organisation pushed quite strong to implement the changes in a short time for most of the fleet. A nice example of the strong promotion is a brochure of the 1930’s describing all the advantages of the Tall Marconi Rig for the owner (taken from “A History of the Star Class - The First Eighty Years” by C. Stanley Ogilvy):
