Sorry Milton you've got the stuff going around - I just got over it a couple weeks ago. Sure went thru the Kleenex.
Anyway, I tried your last suggestion and as you can see - no joy. I am showing contents of sim.cfg and Aircraft.cfg files.
IMHO, I don't think the aircraft.cfg is required for any AI aircraft/boats - I've managed to make them work without with it.
Sim.cfg contents:
[contact_points]
max_number_of_points = 5
point.0=4, 3.635, -2.170, -2.30, 3000, 0, 0.00, 5.00, 0.25, 1.60, 1.00, 0.00, 0.00, 2, 0.00, 0.00 //front left of boat
