You are the first player, and you take your turn as normal, with one change:

When you cross the Ship Line, the Solo Pirate will sail the ships. If it has to make a choice, it prioritizes sailing vertically before horizontally.

Merchants: If possible, the Solo Pirate sails each Merchant to the adjacent Map Card that will take it further away from you (as long as that location is still advancing toward its Port). With one exception: a Merchant WILL NOT sail onto the same Map Card as another Merchant, even if that means sailing it onto your ship’s Map Card. If it is possible, move the Merchants in a way that will avoid this conflict.

Navy: Sail vertically until it is in your row, and then sail horizontally toward you.
