Everyone should have a sheet in the NS dump. If you don't have a sheet in the dump, you cannot post.

Also, cannons on Galleons, Battleships and the like are more common and acceptable than Land Cannons

From the late Middle Ages onwards, warships began to carry cannon of various calibres. Although some 16th-century galleys mounted broadside cannon, they did so at the expense of rowing positions which sacrificed speed and mobility. Most galleys retained a naval ram as their most effective means of sinking another ship. Most early cannon were placed in the forecastle and aftercastle of a ship where they might be conveniently pointed in any direction. Early naval artillery was an antipersonnel weapon to deter boarders, because cannon powerful enough to damage ships were heavy enough to destabilize any ship mounting them in an elevated castle.

It can be assumed Land Cannons use bigger calibres than Naval Cannons, as LCs need to punch through the densely packed stones that make up a cities walls and fortifications, wheras NCs only need to break through thin layers of wood.
It also means that NCs will struggle to effectively damage a rock wall or fort, so anyone hoping to use boats as a means of wrecking enemy fortifications should focus fire on the soldiers, not the defenses.
