Pirates and seafaring traders!

Villages have docks, so why not make them useful? Please add boats (like the shipwrecks in the ocean) to go on these docks, and a way to make your own bigger sailboats that can travel the high seas. There can also be seafaring traders, like merchant ships. Pirates can also sail the seas and try to attack merchant ships and villages. Similar to raids, but on the water. There is also great loot to be had on these ships, like diamonds and armor trims. I think you could add a block that turns the ship build into and actual boat, and add cannons for naval warfare. There WERE cannons in medieval times! Mojang, please please please add this!
