The Naviga M section rules for 2020 have now been published. You can find them here:-

I have had a skim through and the main changes are:-
- Boat colour clarified. A single bright colour which contrasts with the water is allowed. This can’t be white.
- Limiter settings and use outlined.
- Limiters mandatory in non mini classes and are provided by Naviga with specified connectors.
- No turning back if a buoy is missed.
