I wonder if anyone has a good solution I can use?
In the sailing instructions the course diagrams usually come from a standard set which in many cases come from the MNA. When running offshore the course is often set up on Navionics. I have been trying to find a simple drawing program where I can draw myself some alternative courses, as we use in some of our Regattas. I tried Boat scenario but it is not set up for that. Preferably Android/Windows operation. What do people use?
