Mistress Rosalinda
Guns in the Great Cabin in the days of the real HMS Rose were 9 pounders and up. When in action the Captain's Cabin became another fighting station for, in most, cases 4 more great guns( 2 larboard and 2 starboard) Some ships Great Cabins would have fake guns made of wood. These non firing cannon were called Quakers after the peasefull folks who would harm no one.
The cabin's forward walls were canvas stretched over a wood frame, as were the walls of the other officer's cabins and the gunroom. In battle these walls , along with all furnishings were placed in the ship's hole for safe keeping and to give the men room to fight the ship(work the great guns )
Raking a ship( firing as you sailed past ) was best from the stern (aft portion of the ship) This would send cannon balls down the lenth of the ship's interior, overturning cannon, killing men and sometimes damaging the ships mast. It was a most damaging act upon a ship.
Now Ye knows.
