Down sized from macgregor 26 to an Oday 17. She's a 1979 model and well cared for. Was looking for something I could handle better myself. Soooo excited to get her in the water but I am having a problem figuring out the rigging. There is only 1 piece that came with the boat that has a dead eye ( I think that's what it's called) with two pulleys and a line attached which seems to be long enough to be the mainsheet. I have spent hours online searching for a diagram of how this attaches and where. Any help?
