I’ve been on this boat several times. The main access to the passenger sleeping are is the staircase near the galley. There is also an emergency escape hatch at the back of the sleeping area near the doorway to the back deck. However there’s no way 34 people are getting out that hatch in the event of this type of catastrophic fire.
Horrible. Normally these things are perfectly safe so nobody ever considers the what if.
If the fire started in the galley...
