If Im not mistaken doesnt parking in the very end of the hangar bay put you in more danger of getting smacked into a wall when the ship turns? You should park where the ship's center of rotation is before you start thinking about shooting it, that way you'll survive a bit more often when your victim makes a snap turn.
As for taking the Ves down... ive always preferred a salvo of Dumbfires if available instead of torpedoes. Much more power usually at a lot less lock time. And with the Ves, no chance of missing. Full charge from the Fissions, rip off the DF, another burst of fission, and voila! Watch the crate fry. In theory. Ive never tried this approach, and cant verify it for you because someone else has my WC4 copy. anyway...
