Just bought my first Nacra and have a few things to be done to it,The Tramp needs to be replaced and on the starboard hull the tramp track towards the stern the rivets are pulling out.So can i just drill the old rivets and replace with new or do i need to put a deck hatch in.Is there a backing plate for the tramp track or washers etc etc. Any help would be appreciated i dont know if all Nacra's are like this or not i have an 84' 5.0 Thanks in advance.

Do some searching of the forums. someone fairly recently had the same issue with pulled rivets that you have. I can't remember the exact fix, but it was rather simple.
