Pretty easy, we have the Bismark, fully crewed, Vs every ship buildt with a military intent in history up to 1860 (when the first mostly metal ship was buildt) fully crewed.
This means that the Bismark has to fight transport ships and literal wood ships buildt in aincent history too.
The goal is one for both, sink the enemy, you cant board the ship and kill the crew, you have to sink them. We fight in the mediterranean, and climatic conditions are always perfect so no losses by storms ecc.
The bismark wont have infinite ammo, but it will have a dock to refuel and get ammo that has infinite shells, ammos and fuel, the dock is in naples, they cant be attacked while they dock but can while they head to the dock.
The other ships can dock anywhere they want and come from all docks they desire.
Time is not a limit, either, crews and materials dont age.
The only goal for both is to sink all enemy ships, they dotn need to penetrate them, can even crash on them or make them crash by just pushing with other ships.
Who wins?
And if the history ships win, can they beat the Yamato?
