Thanks for all the advice. I finally got in contact with Nacra Europe. It took a few phonecalls, they just dont call back...I send the pictures and now they want to take a look at the boat. They have 5 years guarantee on the hulls, but after 2 years it is not 100%. Every year it is a few % less. But i doubt if its a guarantee question. They told me that if the bridle was bad from the beginning i should have problems earlier. I think its better to let them repair my boat. I could do it myself and thats a lot cheaper but it would be better if they do it. They have the knowledge. Its also better when i want to trade the boat for a new model (Infusion/Wildcat/Shockwave). I let you know how this story ends. I hope i am sailing very soon.
