Actually for the WW1 torpedo boats, the answer is still pretty much the same. The attack was normally conducted using either the port or starboard torpedo tubes, i.e., the forward ones with only limited traverse on each side of the hull and the right or left pair from the angled midships mounts. The torpedo boat would approach the target at an angle so as to show as little of its hull as possible, and once in range would fire the first salvo of torpedoes. The angled midship torpedo mounts facilitated this and required only a little traverse to train one of the torpedo tubes off the port or or starboard bow as the case may be. The torpedo boat would then either turn away rapidly under smoke screen or alter course enough to bring the unfired tubes from the other bow to bear and train the center tubes mount over onto the proper bearing so that its unfired torpedo tube was aimed along the same line of sight as the forward tube.
Their shoulders held the sky suspended;
They stood and Earth's foundations stay;
What God abandoned these defended;
And saved the sum of things for pay.
