Thanks for the feedback.
Turns out my bathroom bag swung and hit the latch. The trip hole didn’t work. I ended up removing the hinge pins which were conveniently located on the cabin side.
I’ll save the master key for my next adventure. Stay Salty!
While running around the gulf, I found the bathroom door locked with no one in the head. How do you unlock the door from the outside? I have a 330 Express.
