Ok, there is one continent with a huge sea that eventually leads to another, smaller continent and there are many islands scattered all over the place, some big, some small. Each continent is about 3 times the size of maplib and the ocean is about the size of the current map. (From what I hear the new map will be much larger so this is possible.) Plus there are a whole bunch of stuff in the ocean like whirlpools and sharp rocks that shrink your ship.
And there are a few different types of ships with small rowboats you can build and add to it as lifeboats. Unlike the rowboats, you are able to walk around on the ship and go into places like the captains cabin etc. To steer the boat you need to be at the wheel.
If combat becomes more common and the death penalty is lowered then we could have massive naval battles with cannons and boarding the deck of another ship etc.
What do you think?
