I have a 32 I'm fixing up. Very sturdy boat. There isn't a lot of info out there on these and each year there were changes. A lot of the
repairs are going to be very similar to any other model. There's a thread called "Challenger 32 ?" that has a lot of good info in it.
If you go up and click on "Community" and then go down and click on "Social Groups" and then search for Challenger, there is a Challenger owners group.
