Almost hit a Green Marker Buoy today...some-one was looking after me.ha!ha!..Was heading down the river and going about 18 mph.... I saw the green marker on my GPSMap and visually...pass by it almost ever day. I don't known what happened....(probably a lapse in concentration )..i lost sight of it behind the anchor/bowroller setup and thought i had passed by it. Well i hadn't...i don't know how close you can get to something without hitting it but i am talking inches if even that.Has anyone else experienced problems seeing over the bowroller and anchor while navigating.
