Best Defense against ship capture?

[NullAshton]

If you have a self destruct device, then when your ship is successfully boarded, both ships self-destruct.

I THINK the master computer has to be destroyed before you board a ship with it on.

The best defense would be security parties. That's what they're there for. Security parties can defend against a larger amount of boarding parties, you'd need only about half as many security parties as your enemies boarding parties.

Shield regenerators might be good, since your shields have to be down before you're boarded.
