Agree, the passenger/cargo ships seem to be the worst.

Okay, so there is no immediate feedback that a target is history?

I believe if you are within detection range of the ship you will get notification when it sinks. This may be within hydrophone range but beyond visual range. If you are within game-rendering distance of the ship (which may be beyond visual range), and you have map contacts on, you may see a grey icon appear when it sinks, but I believe there is no "She's going down!" notification.

So, what do most people do then, just put two fish into something and leave it be?

I'm using GWX3. Generally speaking, I put 2 fish in every ship I want to be sure sinks. I do this especially in bad weather where I cannot use the deck gun to finish them off, or later in the war when everyone is armed.

During convoy attacks, I'd say that about 25% of the time a single torpedo will cause the ship to explode and sink. It's both fun and sad to see a ship explode on the first hit and then see your second torpedo also plow into it. Fun for the bonus explosions, sad for the wasted torpedo.

If it takes one or two hours for it to go down and you have sailed off will you still receive credit or do you need to maintain a certain range?

See my comment above. It depends on how far away you get from it before it sinks.

What about the deck gun? Just aim for the waterline or try to start fires on deck?

Rumor has it that shooting below the water line is the best way to destroy ships by gunfire. I'm not really sure.

Final question: I am confused on to fish settings. Should I go impact or magnetic? Should I set depth to hit the hull or go with magnetic and pass underneath?

In GWX (and possibly stock, I cannot remember), magnetic torpedoes are prone to pre-detonation to simulate the historical problems with magnetic pistols. However, in game, they never malfunction inside 1000m, even early war. So you may use magnetic pistols with impunity to attack targets within 1000 meters.

If you are intentionally using magnetic pistols, you should aim about .5 meters under the target draft so that it passes closely under the target's hull.

My understanding is that if you achieve a standard impact hit with the magnetic pistol on the impact pistol is what does the detonating.

I believe I have read people say you can make high-angle impact shots with the magnetic pistol and it will detonate on impact anyway even though the impact pistol would not work at such glancing angles. I don't know if that is true or not.

I only use the magnetic pistol when purposefully shooting under targets.

I mostly use them for killing pursuing escorts with down-the-throat shots.
