New Rail
Sorry to hear about the damage to your boat. The OEM of the rails used by many if not all Catalina's was "Railmakers". I have sent alomg the link to their website. I contacted them a few months back as I accidently bent my stern rail while securing my dinghy to the davits. They responded promptly, and the cost of replacement seemed reasonable, however the freight was almost as much as the rail itself. They did suggest how I might be able to repair the existing rail. Give them as call, and explain what has happened and see if they can help. I found found virtually all of the manufacturers that Catalina uses to be extremly helpful, and often times "bend over backwards" to make a situation right. Good luck.
