If I were in a boat surrounded by sharks, my first and most important action would be to stay inside the boat and stay calm. Panic, flailing, or trying to enter the water can attract sharks and signal distress. I wouldn’t lean over the ship or put my hands or feet in the water. If there were any fishing bait, blood, or food in the water, I would try to carefully remove it if possible, since these are what likely drew the sharks in the first place. I would also move slowly and deliberately to minimize any sudden movements or splashing, which sharks can interpret as a sign of a struggling animal. The goal is to make myself as uninteresting as possible to them and then, if possible, slowly and carefully move the boat away from the area.
I can visualise you every movement Christian. Very careful indeed, but the simple solution to that is to stop imagining in the first place. Gott yah
