I mean like a stance or something without grasping an object like a rope or other solid object to not sweep away. When I mean armed I mean something like a sword, spear, or other melee weapon.
The example that I found regarding armed fighting on ship is from another SE, but I cant read or get the context.
From the Royal Museums Greenwich Instructions for training a ships crew in the use of arms in attack and defence by Lieutenant William Pringle Green and another for unarmed from Savate/Chausson/French KickBoxing, but I don't get the context or the application to stay balanced while fighting on ship.
From what I get, it is more about disrupting the opponent's balance technique without context to counter enemy's attempt in disrupting the person's balance.

If this is considered too broad then just focus on the armed technique or trick. I am more curious regarding armed fighting on a ship, minus knife fighting though.
