I'm new to the big boat thing and I have my boat in the water. We hooked up the Genoa and main on Sunday but I have questions about what seems like extra out-haul lines at the aft end of the mast and I’m not sure about how to rig the block for the backstay. Does anyone know where I can get information on how to properly rig the boat? She's a 1987 O'Day 272 LE and I have a spinnaker also.
