Hi
long time since I was flying Navy (SeaLynx GB/Germany)
Normal outfit wood be a dry suit, life west.
Life west would be connected to the dinghy after climbing in (in a box, which is used as a seat)
Three connections, one either side and a third onto the "pull line", which is used to inflate the dinghy after egress.
Dunker training was mandatory at least ones a year.
Stay seated and buckled up until all violent movement ceases.
Jettison door
one hand onto the doorframe to know, where to get out
release harness with the other hand
get out, preferred backwards
inflate life jacket
release both quick release fittings of the dinghy box
get the box in front of you, place both feet against the box and pull the lanyard
after inflating, get in (group with colleagues)
get the dinghy dry
