Certain model of GPS have buoys and channel markers already in them.
The Garmin GPS MAP 76S is one of them, it also has tidal charts. "Bruce" wrote in message ... Hi Guys.... Is there a website on the internet that would give me the exact lat/long location of local buoys to set up my GPS? Many thanks.... Bruce Matthews Monterey, Ca |

hiya
A friend of mine ran into a buoy one dark night in the english channel because he set his gps to the exact long/lat. NEVER NEVER NEVER use buoy long/lats to program your GPS waypoints, you can be sure everyone else is using the same long/lat obtained from a book/chart assisted collision will get you in the end........ Use your brain and program your own long/lat to avoid the brainless ones who use the books. fragged "Bruce" wrote in message ... Hi Guys....

Huh? I agree that you can/should pull buoy locations from a chart. If
nothing else, you get good practice using dividers and learning more about lat and long. BUT........I don't see how you could be any more accurate then actually pulling up to the buoy, current or no. Even if I am missing something, it would be more like 50 feet and not yards. "Jeff Morris" wrote in message ... "Richard" wrote in message t... The book will give you a more accurate fix than trying to take it visually off the chart. I have no trouble getting a very accurate position from a chart. The trick is to use dividers, not just "visually." In fact, I prefer this method, if only for the practice. If you go right up to a buoy and take a fix that is the most accurate. Not necessarily. If there is a current, the buoy could off 50 yards or more. The chart or book should show the average position. And besides, there are lots of buoys I wouldn't want to go "right up to." Actually, the waypoints I use the most are not buoys, but channel locations. It also saves time. I am not saying you don't need a chart. You do. what is wrong with using the chart? |

Well, if he set his GPS to the exact lat and long, why did he hit the bouy?
I think you meant to say that he set his GPS to the wrong lat and long. Additionally, you still have to put in lat and long if you use a chart. So you're saying the books are wrong? Sometimes. But then so are the charts. I think you need to have a lookout!

The buoy locations for the smallest buoys in shallow water with little tide
range might be as good as 50 feet, but the Watch Circle Radius for many buoys is 50 yards or more. In fact, the are 6 categories for accuracy, only the most accurate is better than 50 yards.
