New test with my mod list
- I have deactivated AST_SH5_v2, deactivated AI crew damage control in TDW patcher.
- I have activated IRAI inertia damage test + ship inertia 1.1 at the end of my list (without CTDs BTW)
Results VS a Rongel medium boat with only one torp:
- First test, torp depth bottom hull and boat hitted at the far stern (where are supposed to be propellers) ----> boat didn't sink after 2 hours, still running 9 knots around me!

Had to finish it with deck gun (around me because was surfaced and i think he tried to collide me).
- Second test, torp depth set medium depth and boat hitted right in the middle ----> boat sunk in 5/8 mn !!
So now, i don't know what to think...and what to choose!

What i don't like with only AST_SH5_v2 is boats always stops very fast.
What i don't like with my above settings is when boat is hitted in the propellers he still runs fast...for long.
