Thanks, Jeff nice picture! Very good idea, the location restriction. So, should the text be like:
14. A window in the sail is required. The window may be any shape and placed in several sections.
INSERT: The windows shall reach a point at least 20 cm from the luff or 40 cm diameter from the sail’s tack.
