The Harp
In 1946 Harold Getty wrote a book called 'The Raft Book'. His aim was to write a manual for 'LifeBoat Navigation'. A manual that all ships would carry in their lifeboats. The manual would assist navigators who had the misfortune to have to abandon ship and find their way to land.
The story inspired me to design an app that would be available to everyone who would ever be in the same unfortunate circumstances, or for those who had the misfortune, for some reason, to be without a GPS.
I decided to design the app to incorporate some of the methods the Polynesians used (download my Polynesian navigation App) and also to design some method to find land without the aid of a 'professional' sextant or GPS.
Most importantly, the app had to be useful for people with no real prior learned skills.
This part describes 'the Harp', a 'diy' sextant.
Two simple calculations are included for finding ones Latitude and Longitude.
'On a clear day, you can always see the sun
and with that sun, you never need to be truly lost'
