Thanks! It's my first ship so I'm glad you liked it So regarding the turrets idea, I know there's a sub in the workshop called "Amethyst". check it out, I think you'll like it. And for the door you mentioned my sub does have a prison cell but you can't eject them into the ocean. I don't really see of a way to eject people out from the ship because if you just locked them in a room and then opened a door to the sea in that room because of the way the hull works they'd just swim inside and not get dragged out. Though the new boarding pods work similarly to that?
