The bots use the Ferry following normal movement rules, treating the Ferry as if the clearing with the Ferry and all other coastal clearings were linked by a path. (They score one victory point instead of drawing a card, as normal for bots.)

12.2.1
Closed Paths.
The bots treat closed paths as paths, and they ignore rules for opening closed paths.
12.2.2
The Pass.
When a bot attempts to target a clearing based on highest or lowest priority, the Pass will always meet this condition. (Bots will likely target the Pass, and it will win all tiebreakers.)
