Questions about leaving a division to start a new one.

Hi all!

Just have a few questions for those experienced in this...

1. Is it 10K gems to start a new ship/division? (It's been so long, we weren't sure)
2. Is there also a minimum career rank requirement to start a new ship?
3. Obviously the person who purchases the new division ship becomes default Captain - but can that Captain transfer power if they wish to?
4. Can only the Captain promote/demote Co-Navigators, or is there a master setting to allow Co-Navs to manage this too?
5. What other settings does the Captain have that the Co-Navs don't (besides ship description and icon, open/private status)?
6. We've heard about some umbrella divisions managing multiple ships, rotating leadership etc - what are your thoughts on this (pros and cons)?
7. Before we 'jump ship', are there any potential risks we may not have considered (besides starting from 0% upgrades)?

I'm sure there will be more questions, but if anyone can help with any of the above, that would be greatly appreciated - thank you!
