Sailing ships

You can build ships with wood and then place helm to where u wanna control the ship from, you can design it however you want, each part of the ship would serve its perpose and it would give players the freedom and creativity to build. And also the ocean is lacking on action on the surface, like pirate raids, pillagers on ships! That would be epic. And also a new npc that you can talk to that's spawns near a sea, you would need his help to build ship parts, of that would be a unique mechanic (just a suggestion)
