I too recently got an 86 H31. It did not come with an "owner's manual" as such, but a number of things were included in notebook, some of which represented add ons, and some probably OEM equipment. There was something on the mast and spreaders, I think. I'm sure you already looked at the specs provided on the Hunter website, and the one Steve provided. If there are specific things you are looking for, I will try to get them for you. Is it very likely any of the running rigging is what came with the boat? If you want to communicate off-site, would be happy to share experiences, improvements, projects, etc. Steve remembers more about the 31 he had than I will ever know about the one I currently own. How long has it been since you moved up to the 36, Steve?
