Hi Robert
I just set this up for our regatta over the weekend. The start/finish line remained the same but the windward mark (WW1) moved a little from race to race. I simply added another start to the regatta, then added another top mark (WW2) for races 2 & 3 & added it to the list of marks rather than WW1. You definitely can’t move the original mark because, as you found, that affects subsequent races.
