@~34:29 the Cannon is loaded & ready at 8 seconds. This is A Clipper Cannon, when the Average for Loading/Reloading is 2.5 min average. The WWII Battleships Main Turrets (Cannons) took average of 25 seconds. Plus in reality it was not actually completed (Loading) until the Cannon is also returned to proper spot to Fire. She has to push it into place. Those Cannons also took 2-3 people to move. Of course this show does a lot of "Subtle" Parody.
