Hello geosub1978,
My previous modification restored the bowthruster engine and main engines data to their original values, as was indeed needed.
What I don't understand is what you mean by inertia, as the displacement is set at 4775 mt, and the yaw, pitch and roll are computed and should have matched the mass moment of inertia values of the ship. But indeed there was a mistake in the yaw radius of gyration, 21.65 m ipv 19.22 m, which is now corrected in the attached file, you have been right about it.
Speeding faster would mean higher thrust, which is quite improbable: The peak thrust is 775 kN for each propeller, 1550 kN both, the mass of the ship is 4775 mt, so 1,550,000 N divided by 4,775,000 is 0.325 m/s² at start time, of course propeller efficiency changes with speed, so does water resistance. By the way, the static wetted surface is some 1800 m².
I do agree that improvements are needed, I think because this version of Sherpa doesn't exist, such pods aretoo heavy at her stern, 80 t each probably. But why not? The best way to have correctly set values is that you would give me the name, particulars or specifications of the ship that you intend to simulate, as rolling data and accelerations, maximum values to be expected under the developed thrusts seem to be not far off in the FairmountSherpa model.
Videos of the intended ship could also give some idea of what you mean.
About your second question, well, I don't understand, when the camera is used, the keyboard controls should be active, only the walkthrough mode precludes their use, doesn't it?
Regards,
Luc
