Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

At the A&R shipyard in Germany, the successful principle of SWATH boats was further developed in 2013: The SWASH principle allows sea-going, smaller and more economical boats.

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.
