Fuck up. We have in our manoeuvre manual a special section for certain situations you want to avoid but you have to deal with. One of these special situations is when your gennaker wants to become a submarine. Another situation is when the gennaker wants to become a bird and flies to the sky. Because of our manoeuvre manual we were able to deal with submarines and birds. After we educated our gennaker we surfed down the waves and Percy set the top speed mark of 19,4 kn. All are well.
