Can anyone tell me where to find a basic diagram of how to properly rig a Gennaker? Or at least a plain English description? We have an Oday 222 and have only been sailing since last Sept. We've used it with the tack attached to the deck like the jib and also with a short line (home-made on our best guess) from the deck to the tack. We've been running the sheets through the blocks we use for the jib and Genoa. Are we close to rigging it right? What I've found on the internet indicates that there should be blocks for it mounted aft, but I'm not sure how far back and where.
