Axelle Pillain from France is the reserve female sailor for team Malizia - I think I saw her on the Eurosport-Live this morning.You can put money on it that a replacement has been organised, just in case.
My bet is that she will be rested till Newport. That will give them time to assess her condition. Problem is that Boris is being swapped out for that leg too.
Still not sure if she will replace Rosalin the next leg.
