Here the captain of The Lady Mehley explains what you can do onboard the ship during its voyage.
Marine Anderson explains the crew's presence on the boat.

He seems stoked!
Onboard the boat from Ratchet to Booty Bay, you'll find the ship's parrot mascot, Treasure. Also note that you can stay mounted onboard the boat!
