What were the dimensions of a ship's main cannon in the 18th century.

I want to make a scale replica of a main cannon on a 18th century pirate ship and I am having trouble finding information on what was standard sizes on them.

What pirate ship, how rigged, what nationality/region, and what part of the 18th century? And what do you mean by "dimensions" -- do you mean weight of shot, or length/diameter of the gun barrel?
