A boat equipped for it sounds fog signals and shows lights under the IRPCAS (COLREGs) or local rules. Boats comply with IRPCAS rule 10 on traffic separation schemes; the notice of race may substitute a section of World Sailing's Appendix TS. When a rule requires an AIS transponder or other tracker, you may not turn it off or reduce its effectiveness on purpose.
