I think it`s not really important if the simulator be very accurate or not with the official nautical charts of every scenery. But would be necessary documentation and information about what VStep has made at every scenery. There`s no data in the nautical chart. The echo sounder shows the depth at bow and stern; with positive trim, but VStep doesn`t give to us any graphical information about what we shall find along our navigation. Is one of the many incomprehensible things of this simulator; the lack of information. Couldn`t VStep make scenery depictions with the depths and other marks. We could print in our printers the maps and plan our navigation.
Every day more and more merchant seamen, nautical students, are writing in this forum. Really amazing and important. This people knows about they are talking. They can spur forward VStep.
We will be tireless in this question. If you make a simulator, it`ll must be complete. There are many simulations in the market: cars, planes, cranes... At the very beginning you will concentrate your efforts in the dynamics. But a vehicle is immersed in one environment where interacts with that environment (winds, rain, fog, tides, streams) and interacts too with other vehicles. Unavoidably you are forced to implement rules, operative procedures, codes.
