"My" carrier model is just the simple one that comes with the sim, there's a full-on one comes with acceleration
look for
C:\ProgramData\Ideal Flight 10\Profiles\boats.ini
add:
veh_carrier01_high_detail_sm, Detailed Carrier, 0.1
there is already:
VEH_carrier01, Carrier, 0.1
0.1=fraction of full speed
