they're just releasing brigs which is kind of a ship of a line but its a whole class higher than frigate. they also releasing ship upgrades and design such as a theme of the ship the kind of looks like Queen Anne's Revenge (blackbeard's ship) design called skull and red or something and gives 15% chance of broadsiding fury. you can also change the color of your sails and paint emblems on them. do do most of this you need to gather materials into your material pouch (pinecone, gold, etc) and bring it back to the shipwright and select upgrades
