My ship would have 12 sails to move through the seas. It would have 30 broadsides on each side as well as 18 cannons. 3 in front(2 on either side of the front, one in the middle) 2 up above,4 on each side, and 5 up where the captain is. One of the cannons would be directly behind the captain in case of attack from behind the ship. The broadsides and cannons only fire furry or lighting as well as a grapple hook.
The cargo hold would be divded into 2 sides..One side which can hold up to 65k gold and the other side which is for prisoners. The sides are divided my a double wooded wall.
