I would like to enter waypoints by typing in their lat and long into Navionics HD UK Holland on an android tablet (a Hudl - yippee). Is this possible? Thanks (PS what about a floating crane?)
I could be wrong but when you (I) touch the screen it comes up with the lat/long and allows you save as a waypoint I think.
Re your PS I think a carefull survey of the ground already covered would highlight the impracticality of your suggestion, although I don't know whether you think you could afford the time.
