I understand is terrible difficult to develop a variable draft in real time for the ships en Ship Simulator. I remember too in Ship Simulator 2008, VStep designed a special version of Lattitude; with a reduced draft to use the ship in more ports. Maybe could be possible to design different versions of every merchant ships: Vermaas, Lattitude, Jumbo Javelin... with the ships unloaded, half loaded and fully loaded, for instead. At every situation of course, the performances of the rudder and the propellers would be differents. We can`t think to have a variable draft in real time, at least for now, but a first approximation to the question would be interesting.
I like very much the Agile Solution. I consider is the most versatile ship in the simulator to do the "experiment" described in the past paragraph. If VStep designed a special crane to load and unload containers, why not handle the cranes in the Agile Solution, and open or close the hatches of the cargoholds?
