It has to be a pretty big crash now to lose much distance while racing, mild "crashes" when the hull just comes back into the water are not too major.
The top guy/s are foiling around the course 99% of the time, even during tacks when needed.
It all depends on conditions, but looking at the VYC yardstick. Foiler Moth - 83, A-Class - 71, F16 - 71.
Yes, but how much do the YYC adjust based on performance, is it like the US where you only move 25% per year ?
IU'd bet that the Moths were getting 25% faster each year.
