Note:

This is a new page for displaying documents. The first time a document is loaded will take a little longer than it will for the next person so please be patient if it takes time. It will be much faster once all the documents have been converted. This will also allow these documents to display on devices without pdf viewers specifically mobile devices. Please email me at "L-36" dot COM if you notice any strange behavior. This is part of the Google requirement that all web pages be "mobile friendly". This is an effort that takes quite a bit of time and as it is just me and I would rather be sailing...

Note also that some documents have blank pages. Just click on "Next Page" if that happens.

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.
