Just after fixing the ship one can pickpocket Aloth below deck for any quick items he has equipped.
Every time one leaves and re-enters the cell his pockets will refresh and those items can be stolen again.
One can even add him to the party and change the items that he will always have available to steal.
This is a very easy way to amass a large fortune or create large amounts of rare combat consumables or traps.
This bug was not present for other companions at this phase of the game, e.g. Eder, Xoti, and Serafen.
