Hey Macca,
These are still quiet new beasts..... How much are the skippers (including those who saw the begining of the class) going with regards to familurising themself with the boats behavour. They look to be a very powerfull boat, behaving more like an OTB cat then a large multi.
As for the capsize.... I think any one of the boats caught in the same position as Alinghy, may well have been treding water also.
