My family had a venture cat back in the 70's. As I recall there wasn't much to the
rigging. A forestay and shrouds. It had a mainsheet with cam
cleats. I don't think ours had a
jib. It was cheap and a lot of fun. It had a rotating mast assy that was supposed to be sealed. Ours wasn't, mainly because it got towed under an electrical powerline on the way to the launch ramp with the mast up and the mast had a couple of holes burnt through it. Oops, never did that again... Have fun with it. I remember it being really easy to flip when the wind picked up.
