Can I also add to the list the Heaven Can Wait regatta sailed out of Toronto Sailing Club on Lake Macquarie. I have never done it but have always wanted to. Initially for yachts only, it was a 24hr distance race doing laps around Lake Macquarie to raise money fopr charity. It has since been expanded to include a 12hr race and also a “one lap dash” for small boats and dinghies. The ‘lap’ itself can vary according to the conditions on the day, I believe.
Anyway, info is here:
I’m not necessarily saying this should be part of a travellers trophy etc, just a fun event.
