It's Team Plasmas boat!
With the damned liberty ticket event. Go to the leftmost pier. The guy next to the blue boat will take you. I think.
Whakaari or White Island is an active marine volcano in New Zealand. It is located 48 kilometers off the shores of Whakatane, and accessible by boat or helicopter.
I think it is just Team Plasma's boat that they used to get from city to city. I can't be too sure but it's not like the others that you can go to places on. So I don't think it's that important tbh. Hope this helps. :) ^ I'm going to correct this person's verison. The black boat is in fact Team Plasma's boat, and it does come into the game. If you get a Liberty Pass (no longer available, but was obtainable over Nintendo wifi) and go to the Liberty Garden, Team Plasma is there. They have heard that a legendary Pokemon named Victini is on that island and they plan on catching it. You will have to defeat all the Team Plasma members and then catch Victini for yourself (it's at level 15) Then, when you go outside you will see Team Plasma getting back into their black boat, they are being kicked off the island. Afterwards, Professor Juniper will appear to thank you. hope this answers your question. :)
Find the lost little girl and play Hide and seek with her, then you will be able to get off of the boat.
The Royal Unova takes you on a round trip back to Castelia City. While on the boat you can fight, but you don't go anywhere.
traveling
It's Team Plasmas boat!
You can't.
go on it and find out.
in castelia city, city with boat to victini
I have a feeling it is the boat u ride to the p2 lab for the genesect event.
To take team Plazma to liberty island.
Well I don't think you can actually get into the black boat as it is Team Plasma's. I'm not sure though but it doesn't seem like you can.
You win it on the royal unova (the boat in castelia city) i think on tuesday
It doesn't do anything that I am aware of, as it is Team Plasma's boat which they would use but it doesn't do anything and you can't board it.
The black boat that can be found located to your left on Prime Pier in Castelia City does not go anywhere and serves no purpose in the game.
