The objective of the course is to teach future deep-sea and oceanic sailors, whatever their nautical qualification, to find Earth following a method with the only help of the Sextant, Spanish Nautical Almanac and Wristwatch; without the need to use a calculator, PC, tablet or GPS.
Differentiate the main Constellations and Stars in the Firmament, with the naked eye.

- DIN A4 squared notebook, pencil, pen, eraser and sharpener.

Course taught by Juan Ramón Pina, doctor. pharmacist, Yacht Captain and PPER.
I started sailing with my 5.5 m BAKUNIN. in length, making long journeys the old-fashioned way: without electronics, or autopilot, or depth sounder, or radio. Astronomical Navigation finished fulfilling all my aspirations as a navigator, training that allowed me to go beyond the Mediterranean and carry out my ocean voyages, which I have never stopped practicing.
At present I am dedicated to the training of navigators in Cruises of Height and Crossing the Atlantic, always following the Petrel Method: guards, kitchen, emergency medicine, sail sewing, sextant and blank letters.
