@Henderson, MÃmir: I'm sorry to disappoint you, but I have survived pirates with my 5k transport multiple times, gunboats and bombers, in house space, on lanes within 20k from a dockable base.
But with a cruiser all you need to do is sit at a jump gate, and wait for someone to jump from the other side.
And I know what some people will say "hire scouts blablabla", and so I will reply "piracy shouldn't be a solo task neither and blablabla".
