When will Puerto Rico return?
The Dockyard with 
VIII Atlântico will not be the last one this year, the next opportunity to build a ship will come at the end of summer (more info will be added here when available), this time, WG will return the pioneer of the Dockyard 
X Puerto Rico.
The BIG Cockup with the first Puerto Rico Dockyard and the changes WG made
The first Dockyard with 
X Puerto Rico was very complicated and not the most successful from the perspective of its design and mechanics, WG have taken all of their mistakes into account and reworked the event design. As all subsequent iterations, starting with
VIII Odin demonstrated, the Dockyard in its current format has become a full-fledged part of our game and works well. On top of that, according to WG, many players have been asking when they are going to bring Puerto Rico back to the game. So that's why they have decided to put Puerto Rico back on the stocks, WG see this as an excellent opportunity to rectify their early mistakes with this feature. It also means that you'll be building a Tier X ship, which hasn't happened since the very first Dockyard. Those who didn't manage to build the ship in the New Year Update 0.8.11 or started playing the game later will now have a chance to do so. Obtaining the ship will be much easier than the first time, but it won't be possible to finish the construction for free, same as with previous ships at the Dockyard.
What if you already own Puerto Rico?
Players who already have 
X Puerto Rico in their Ports but still build her at this Dockyard will be provided with compensation. WG plan to give such players the opportunity to select a bundle with one of the following resources:
Doubloons,
Steel,
Coal, or
Research Points. The amount of whichever resource is in the bundle will be enough to obtain any Tier X ship that will be available for purchase at the time of this event.
