Okay so read before disagree!
Let's say you're sneaking on a galleon! One guy is 'watching' the ship. You climb the ladder and slip into the captain quarters! You see a voyage down on the captains table. IT'S AN ATHENA VOYAGE!
Now normally you would tuck, wait for ages for them to go island to island.. But let's imagine you could pick the lock of the captains table! It would take 30-60 seconds and would give you a journal contains all the ships information and quest voyages! Brillaint! You now sneak back to your ship and start digging up their treasure! We are pirates after all.
The same could work with pick pocketing AFK players who idle on their ship, or sit on the helm without checking behind them. It could take once again between 30-60 seconds for you to pickpocket the players but you could get a piece of the journal, if not all of it!
What do you guys think? Obviously there would need to be a long period of time for you to pick the lock or pick pocket the person. The times are just a sugestion.
