World Sailing also publishes a number of appendices to the RRS and Test Rules that do not appear in the RRS themselves. These additional rules are updated on an ad hoc basis and available for download here.

These appendices and test rules often contain a preamble, which states the events for which they are suitable, and any conditions for their use. Most test rules will require the organizing authority to notify World Sailing of their use and provide feedback to help improve these rules.

Please note that these documents, RRS 86 and the World Sailing Regulations may limit changes that are permissible. Please do not hesitate to contact World Sailing if you are in any doubt about using these rules for your event.
