Hi all: I am the type of sailor than is constantly watching out for other boats. I make sure I stay clear of them whether I have right of way not.I think most people are like that. Or at least I thought! why not change course a few degrees to avoid a distant boat and perhaps a snap decision when you get to close. I think I know the rules and play it safe. Now the rest of the story. Friday I was sailing on a large local lake in light winds,on a stb.tack, close hauled, about 2-3-kts. I went out on friday because traffic is light. I saw a small sail boat aprox. 1/4 mi.off my port bow. He was on a beam reach (aprox.)and port tack,and moving fast like those boats do. I saw him look under his sail at least three times and know he saw me, but I kept an eye on him. I changed course a bit and was sure we were ok. He kept tracking me like a torpedo sailing twords me until he was 10ft. away. I didn't have to yell when I said watch it pal. He then poped his head up pulled the rudder and sailed behind me. He shouted I HAVE RIGHT OF WAY! and sailed off across the lake. Now am I missing something here or was I the stand on vessel? If not what could I have done as he flew up on me I can only turn into the wind so fast?
