Annex 1 9b
(b) All-round lights shall be so located as not to be obscured by masts, top masts or structures within angular sectors of more than 6 degrees, except anchor light prescribed in Rule 30 which need not be placed at an impractical height above the hull.
Thanks for finding that.
I suggested in post# 59 that it was worth checking the anchor light complied with legal requirement for all round white lights of a maximum arc where they were obscured of 6°, but it seems anchor lights have an exemption.
