Final comments:
This completes what I set out to do. I am very pleased with the results and what I can do with this set up, where ever I go around the world. But there are some developments that I want but can not do since I don't have the SW development skills. But I know the design parameters to develop it. Its about to maximize the angel between the current wind and the sail. Adding this will need an instrument to provide the direction of the wind to the boat, called windex, usually located at mast top. I invite anyone who would would like to explore this further :)
