Here is some pics of the Nav tour. It went better that expected, not a scratch on the keel.
PS: The drawings are made with paint, and the lines are NOT accurate with the original navplot i made on the map, neither in length or degrees. Its just to show the legs on the map.
Its accurate enough for me!


Conclusion: It is possible to navigate in SHIII using only a stopwatch and prefabricated bearings, and without using the map. The course wont deviate that much, yet it have to be tested on longer patrols.
