AIS ship data: everibody have seen this? - why do we use GPS to track buoys??
"Jack Erbes" wrote in message ... Ted wrote: I don't put much faith in the cry of the geezers about the undisputed reliability of the simple magnetic compass and the paper map. I don't believe that most of them even go boating. They just sit on the internet and run their mouth. ..why I don't have much patience for geezers who ignorantly sing the praises of paper maps as the be-all and end-all in marine navigation and why I don't believe that most of them have ever been to sea. You seem a little fixated on older people and people that use charts. You haven't been paying attention. I'm a little impatient with geezers who lecture the maritime world about how they believe that paper maps are the end-all and be-all of navigation. I have listened to them rant and fuss over the demise of paper maps for over ten years and its getting old. I use paper maps myself but never feel the need to lecture the world about paper maps are the greatest thing that ever will be. I have not yet seen a young person behaving like a geezer. Its always an older person who has fallen behind the times and feels threatened by that fact. Its also very often an overweight older person who is no longer participating in the activity he is lecturing about. It brings new meaning to the old saying: those who can, do, and those who can't, teach. (or in this case, lecture) Take notice of the subject line of this thread. Buoys clutter the chart and provide a dangerous collision hazard on the water. We have put up with this hazard for years because in the past we needed buoys. With the arrival of GPS, they should be removed. http://www.california-car-accident-l...s/pic_boat.jpg |

The Coast Guard also calls them dayboards. If I were to give a legalistic response I would have pointed out to you that I never claimed that the collision object in the photo was a buoy but the real answer is that I'm using the word "buoy" to mean any and all objects placed in the water in an attempt to assist in navigation. Whether the object is a floating buoy or a wooden post driven into the mud or a tower mounted on a concrete base (or even a simple piece of 3/4" PVC water pipe stuck into the mud with a rid tip as is common around here) is irrelevant to this discussion. I use the word buoy because there may be many people reading this thread who are new to boating and might not know what a daymark is. Just about everyone in the world knows what a buoy is. For anyone who wants to know more about navigation marks, here are some links: http://www.auxetrain.org/atn2.html#Shapes http://www.boatwashington.org/navigation_aids.htm http://www.navcen.uscg.gov/pubs/LightLists/Ref2005W.pdf http://www.auxetrain.org/Buoys.html http://www.auxetrain.org/atons.html http://www.auxetrain.org/atn3.html Also see chart number 1 http://www.nga.mil/portal/site/marit...2a7fbd3227a759 http://nauticalcharts.noaa.gov/mcd/chart1/chart1hr.htm |
