USCG Light List and Waypoint Tools
UPDATE: I now download the light list data every week to keep it up to date. It is still not for navigation per NOAA so please double check anything you find here both by clicking on the map functions, and by verifying the locations. As they say, this is for entertainment only. Use official NOAA charts for navigation. Chart numbers will be listed in the application.
This project started out of my frustration in trying to enter a new race course into my GPS. It took hours to get the waypoints and routes in. With these tools, it can be done easily in minutes. The data is from the USCG Light Lists where all aids to navigation in the US and territories can be found and the ones of interest easily tranfered into the waypoint and routes bulk editor where a .gpx file can be created for download to your GPS. Waypoints can be found by simply clicking on a map defining your area of interest. This page is an overview of the tools.
But first: NOT FOR NAVIGATION. Note that what I am presenting is the use of a computer generated data base of aids to navigation. There are two reasons why these should not be used for navigation. The first are the many qualifications outlined by the Coast Guard in the publication. They can move, you might hit what they are marking, and they are not completely reliable. I was once in a race where the buoy marking the start-finish line moved about 200 yards during the race. The second reason is that this data base is computer generated and has not been verified. Basically, you will not know where a buoy is until you have been seen it and taken its position yourself. But this data base should certainly help you find it.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
