How bout firing your last two eels at a modern tanker, in 15 M/S seas, watching them bounce, and as you are waiting for the convoy to cruise on by, you notice something trailing them, yet it doesn't appear on sonar.
When I hit F12 and take a look, since I cannot hit them anyway, I find not one but TWO 44000 ton Aquitania cruise liners, doing 1 knot, sitting very low in the water.
They both succumb to the high sea states within an hour. 88k just gone.
