The Catalina 38 was designed as an offshore race boat and not the same as other Catalinas.
The Islander Freeport 36 is a Bob Perry design however I can understand the error. My wife and I have just made an offer on one here in Puget Sound. We have already had a good look over the boat and pending survey and sea trial she will be ours. It's good to see all the posts about them and things to look for although at this point the items are about the same for a vessel built in the 70's. Ill post more as things progress.
