Thanks,
I am always learning something about NOR's and SI's.

Why elements are included or excluded in the standard SI's is lost when the regatta is handed over to the next team the following year. When you customize it each year and make a minor change...you may find out that what seams like common sense can run afoul of the RRS. You never even think about some of the ramifications.

Ha.. Hobie figured this out years ago... They print the one set or SI's for world wide use and don't let you change anything. The downside is... when you have a multiclass regatta and have to create a new SI's... you do need to know the reasoning behind all of the requirements.
