nationals/worlds

I thought these were seperate events?
How come I can record a DNC in the first race of the nationals when I've only entered the worlds and then only wanted to enter the single handed event.Is sail racer working correctly for an event of this type.

Also, I see from the comments above the results table that Emma and Martina Barry were racing at the front of the fleet but scored a DNC - very rum.

I thought I read somewhere that the Barry's suffered gear failure - broken rudder

Pretty sure Did Not Finish scores the same as can't be bothered to launch (Did not compete).
