Nautical update

Just like our planet, Minecraft worlds have a lot of water. So it would be amazing to be able to build a Ship. It would add a whole new dimension to the game.

All the benefits ship update could bring:

-Building ports - giving aditional value to villages next to the coast
-Pirates (like raid but on sea)
-Transporting goods over distances (chest on ship)
-Living on a ship (placing a bed on a ship)
-Easier Fishing
-Customisable sails or flags (like banners)

In adition i feel like a river update would be beneficial so that rivers would not begin and end randomly but would be longer and always conect to the sea. This would also give great use to current items: Compas, maps, spyglass.

Aditional sugestions in coments are very welcome!
