The utility (Plug-in) uses tidal data from 14 standard ports to calculate the streams at over 1900 tidal diamonds, with Dover being responsible for the huge majority of them. Current time can be used, or dates and times selected. Springs and Neap rates are automatically calculated hour by hour dynamically and displayed on the base map.
It can be used in a separate window from other navigation programs, such as SeaClear to help plan passages using the tidal streams, and comes with a base map. Using it as a stand alone with the base map will quickly give you the tidal stream information you need.
It uses the free OpenCPN open source software, which has been configured to run as a “portable” application. (ie: needs no installing and will not interfere with any OpenCPN installation you may already have). It has not been altered in any way, and as a lightweight stand alone it's very fast.
