Actisense Ngt 1 User Manual Issue 2.01


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...

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
