When I am going to board something that has a speed over 100m/s I always stock around 10 disruptors, and MAYBE use 2-3, I know you can't buy them but you can get these easily in the game just by doing 4-10 protect/defend/patrol/escort/assassination missions.
I know the most common tactic is to use Ion Ds but the Disruptor Missiles have the added bonus of 0 unintended splash damage... just sayin'
