Brigantine not in Sea of Thieves? Glitched? Misinformed?

I was told that The Brigantine was added in the recent update. Because I was dealing with the whole lavenderbeard situation, I deleted the game and downloaded again because I do not know how to delete an update (I play on Xbox). When I launched the game I was very disappointed when I did not see the option to pick the Brigantine. Was I so excited that I got naive enough to get tricked? Or was the Brigantine actually added to the game and it just did not appear? Nevertheless i need someone to fill me in on whats going on
