ok i notice this... at first i couldnt even see your target and assumed the video was too dark on my screen - then i realized... your target almost fills the scope sight.
what do you assume the range to be? under 500 meters? are you super close?
your torpedo will have to travel a minimum of 300 meters to arm its warhead.
it is very possible you are sending a spread of three completely unarmed torpedoes into the hull of the merchant.
