Remember,this is all inside the turret!
I would not want to be occupying this seat during any battle, let alone a practice run!
3 cannon firing at once, or sequential had to be unbelievable, with two more turrets of 3 cannon, firing 16" projectiles. If they were firing with the cannon at right angles, the blast would actually push the Battleship sideways, even though it was All Ahead! There was plenty of refills below decks! I don't know how many men it took below decks, lifting the projectiles with chainfalls, placing on racks with rollers, sliding them forward or aft, along with another crew doing the same with the powder charges, then into loading tubes up to the turrets. What an operation,it must have been. An everyone had to rely on everyone else! YOUR life depended on it!
Yes its tight..You needed someone to turn it, lift the 3 cannon up & down, someone reading angles, heights and figuring the distance to shoot the projectile. All this while the ship is rockin and rollin,tremendous noise and heat? On top of that you needed to keep your thoughts positive, not worrying about the vessel your are on could get hit! It had to be scary, but who had time to worry during a hot an heavy battle? I couldn't imagine being a gunner...
Thanks for the tour Ron!!
