I did mine. Venture 25. Look into the the past forums here for specifics. On the 25 I think it is 12 feet. BWY could tell you. I had a local rigging shop make a couple for me. These guys are used to making crane hardware so it was fun for them. I had them make all of my standing rigging. Very cheap. The owner ended up giving me the fore stay and swage for free. I call to say hi, chat and thank you from time to time.
