Remove “A Sailor may not voluntarily become a Prisoner. The captain may assign Prisoners as normal. A Prisoner may not voluntarily change their position.” from the ruleset.

Add a new subrule to “Positions”, called “The Prisoner”:-

A Prisoner may not perform Job Actions, Encounter Actions or Gam Actions, nor may they change their own Position.

If more than one Sailor is a Prisoner, then the Prisoner with the highest Prestige may set their own Position to Deckhand. (This takes precedence over the previous paragraph.)

A Sailor may not assign themselves the Position of Prisoner.
