A buddy of mine has a hooter system for his Inter17. We took it out in 16 kts down wind and had a blast. The only problem we had was after winding it up and going back to weather the top of the hooter was loosening up at the top and starting to flap. After several attempts rewinding the hooter it was still coming loose toward the top and flapping even though the bottom was tightly rolled. We eventually lowered it while on the water and put bungees on it to keep it from flapping at the top. The funny thing is that it appears to be wound up pretty good initially and then just works out being loose at the top.
Anyone have the same problem?

Thanks,
Mike
