On the Rawson 30 I just bought, there is a Sail O Mat windvane. I've never used one before and there is no instructions. I contacted Sail O Mat and they offered to send me all, not just one, of their manuals on all models for $50 a pop

. The Sail O Mat website does not offer instructions. Does anyone have a manual or link to a website about proper operation of a Sail O Mat?
