You can quantum anywhere, but crossing a whole system will take 10 minutes of quantum travel.
In the baby PU we only have one planet. It still takes 20-30 seconds for the farther destinations.
It's a few seconds to go from Crusader to its Moon. But it'll be around 10-15 minutes to cross a system. Longer if you encounter trouble.
Multi-system travel could take hours.
On the larger ships there will be things to do while traveling.
I would think you won't travel in the turret, but instead run for your assigned spot when the Captain signals "Red alert"
I'm not the best at GPS, but I listen extremely well during previous raiding in mmos and am wanting to be a medic/engineer so I won't need to be in the thick of it.
