Has anyone entered a ISAF Category 1 race with an Amel? There are some rules to which Amel may or may not be built. For example, there is an OSR 3.12 that states "The heel of a keel stepped mast shall be securely fastened to the mast step or adjoining structure" which could mean I need a bolt through the mast base. If anyone entered Category 1 race before, quick list of things you added/modified would be priceless.
