I dont think this has been mentioned.
If you camp while in a ship (yeah yeah pretty stupid thing to do) and go walkaround instead of being able to walk up and down the ship it takes you to normal battlefield with grass and trees etc.
Also when you stop the camp instead of going back to a boat it goes to the horse (or man, depending on if you have a horse).
I say instead of CAMP you need to change it to DROP ANCHOR
