I think Houses should have a lake and a dock with all the ships of the house owner docked at it. I also think those who are at a player's house should be able to unbottle their ship at it. Then I think the house owner should be able to set up controls that allow player vs player ship battles in their lake. The options would be to allow them attack anyone, to disallow them no one can attack anyone, and to pick sides. The house owner would select which ships would be on which sides and which teams for fun ship wars and to see if larger ships can hold off against lesser ones. People would go to player houses and enjoy themselves sailing in their lakes and picking teams for fleet wars. Nothing rated, just for fun.
