An example depth calculation:
15 m/s wind x .4 = 6m deep torpedo.
This particular formula (known as depth 2 D2) is to calculate the deepest you can set your torpedo at whatever wind speed storm you’re dealing with, to lessen chance of premature detonation. You could always go deeper so check the draft of the ship.
If you wish to go more shallow then here is the next formula (D1):
15 m/s wind x .25 = 3.75m deep torpedo.
D1 is a shallower depth you can use when you want to impact the ship or if the ship has a small draft. D1 has a slight odd of premature detonation, but offers a shallower depth for impact pistols.
At 60 m/s wind, as example, you really have to consider attacking the boat at all, or follow until the weather changes! D2 at this wind speed is at least 24m deep!
