From Antonio Bari

Summary: to delete the minimum thickness requirements for fiberglass hulls and cockpits

 

Affects:

     Constitution                       By-Laws                   Class Rules

     Deed of Gift               Rules of Conduct        NoR or SI Template          

     Other

 

 

Objective: The requirement is difficult to control; it is intended to grant stiffness to the boats, but the class has the minimum weight and the MOI test rules which are sufficient to guarantee quality made boats.

 

 

Proposal (include current & proposed changed wording- changes to be shown in red):   Example: By Laws: Section 1. Racing Season

   The official racing sailing season of this Association shall extend for the full twelve months of the year starting on January 1st and ending on December 31st.
