Basically players can go to docks or shore line near the upper maps and create ships that would sail the seas, have storage, and fight other ships.
I'd like to see Ship fights not involve players lvl(cause that's already on land), but instead the crewmembers skill of maintaining they're vessel and ships.damage capping, at a certain point, but players can still reinforce the ship a lot more, boosting hp with planks, or adding armor to the ship with steel that will wear with use.
Different ships will have different advantages/disadvantages, attack ship with faster fire rate or more damage, supply ship with lots of storage less attack, etc.
Maybe a shipyard can be added where pvp is off in that area so people can build safely then fight at see if they want to
There's a lot of pottential with all the water to the north
Ok, shoot me down now

Constructive Criticism is the key
