Allied vs Axis anti-shipping tactics and weapons?

[Lucky13]

Seeing that the Allies had bombs, depth charges, rockets and torpedoes for their anti-shipping business, did the axis have anything at all in their arsenal matching the 60*lb one with high explosive and the one with a 25*lb armour-piercing head of steel - known as the 'Rocket Spear' and what about depth charges? How does all these compare?

Oooops.....almost forgot those Tiny Tims!

How does the success rate between the two sides compare, losses vs ships sunk/damaged?

Leaving out the Fritz X and Henschel Hs 293 in this, since they're more like guided missiles than rockets....

.....and did they use similar tactics, or were those quite different?

Edit: I knew that I forgot something, cannons!

Accurate enough and powerful enough that these dive bombers were always dangerous to enemy ships. Even if the pilots normally received no maritime attack training.
