I am trying to make shallow torpedoes, but problem is with right angle I guess. But to get 90 degree is so hard for newbie.

That scheme explains lot, thanks.

BTW - how You deal with speadboats if You can not use a deck gun because of weather? What is tactics against warships when You can not use torpedoes? Dive and tray to slip away while repairing damage?

Thanks for answers.

Personally I would refrain from attacking warships as much as you can,after all,UBoats were designed to sink merchant shipping (ideally when undetected),the surface fleets are designed to engage warships in a duel.
HOWEVER,there may be times when you are evading a warship and he is perfectly lined up for a stern (rear) shot as he chases you (it is possible to lure warships into chasing you and you are at periscope depth moving away from him,then you can force him to run into one of your stern torpedoes),and the rare moments you may get the chance to sink a capitol ship/battleship etc etc,in which case an attack would be too irresistable to refuse!

And forget speedboats,they are not worth the time and effort,giving something like a meagre 50-100 tonnes? for bagging one,simply evade them and stay down until they are out of sight,then surface.If you REALLY wanted to attack one maybe using the AA guns would seem a better choice.
