1.  Overview

----------------------------------------------------------------------

a.  Opencpn was built with the following objectives in mind.

    i.   Intended use as primary navigation interface for vessels

         with full-time helm-visible navigational suites.

         Other tools may be better for offline route planning, tide

         and current prediction, online logging, etc.

    ii.  Quick startup and shutdown.

    iii. Those and only those toolbar buttons really needed for

         daily operation.

    iv.  Portability, thus wxWidgets core components.  Currently

         tested and in production use on Windows XP-8.1, OS X, and Linux.

    v.   Conventional ( i.e. popular and modern ) chart format

         support.  In the real world, this means BSB format raster

         charts, and S57ENC format vector charts.

        And, of course, opencpn is all GPL'ed (or equivalent)

                        Open Source code.

    Personal Note:

    Opencpn is in primary daily use as the navigation package aboard

    M/V Dyad, a 48 ft trawler yacht cruising from Newfoundland to the

    Bahamas yearly.

    Our thanks go to MAXCDN for providing a CDN network delivering

    the OpenCPN downloads worldwide.

    OpenCPN is distributed using a multitude of licenses, see LICENSING.
