Another update ... I've heard again that there may be a Class40 round the world race. There may be official developments in 6-9 months. I'm going to wait things out and won't look for a boat now. Or more specifically I'm going to focus on finding a used Pogo 40S3 that I can afford.
I'm also going to try to find ways to race on these boats. There's in fact a boat available for charter for the Transat Jacques Vabre 2019, for $40,000. Would anyone be interested?
Still looking for a dinghy too ...
