Pat: I don't think you can find them commercially but they are simple to build. I built mine using oak but got sick of varnishing so I made another one with Starboard. Starboard is the same stuff they make the stern perches out of. After I built the first one, every Catalina owner on my dock wanted one. The problem is, and I already knew this before I tried to duplicate the bow seat, is that no two Catalina's are the same and my pattern would not fit other Catalinas so each one would have to be custom made.The bow perch is a lot of fun especially when the dophin are chasing your bow wave. I have a picture of the bow seat on my web site. Send me an Email at yankee3223@juno.com and I'll provide you with the web site. I can't post the web site here because I sell my products there.
