I was there last week - brilliant event and great experience watching these guys sail - they must be doing about 35 knots down the reaches. The course is a pretty easy 4 bouy downwinder and they always set it in as calm a waters as possible - I'd say our ISS courses are more testing!!! Mind you the wind was 35-45 knots last weekend - I was out on a 3.7, overpowered!!
