Got a swivel cam!
Pretty simple and very cheap. You can do it 5:1 also, I just bought a new mainsheet at 6:1 length and thought that I would see if anyone had a extra block or two laying around, if it doesn't work out then I'll just do the 5:1.
I'll probably post pictures of my in the hobie thread when its done.
DVL(Dale), I'll shoot you an email now, I got your messages on the other forum but not in my email, weird, I'll look into that also. I'm building my sail tube this week so it would be nice to come look at yours. AND hopefully get that double block from you.
