As titled. Ship lockers should work like safes and piggy banks in Terraria. It prevents ninja loot in multi-player and makes ship mods more easily since the locker saves won't get overwritten by new ".shipworld".
I'm not too sure about this - it wouldn't totally prevent thievery. In my case at least. I tend to fill up the ship locker and also many chests on my ship with furniture, ores, etc. The chests wouldn't be safe if this were implemented. It does make sense for the mod argument, but then I'd still have to move everything that's in a chest somewhere else before modding, so it wouldn't really save me too much time.
At least you can put most of your "treasure" in the locker, and put the less important in your chests. If I put my important stuff in the locker now, I have to move 64 slots to somewhere before I mod my ship. And that's a pain in the ass.
