how many do you need?
If you only need 5 or 10 I may be able to send you some. I just bought my catalina 30 and one of the rods was missing! You can't get the damn rods either, but a very nice person on the sail.net catalina list sent me his old bathroom curtins (and rod). If you need more maybe you can get in touch with him (email me and I can give you his email address).
