Newbie query re: mothballing ships.

[Elowan]

Is it a workable idea to mothball hulls with the basics such as bridge, crews quarters, and life support and then unmothball and retrofit as the occasion demands or will you get the "we can't build over 50% yad-da-da-da?"

Or is it better to fully equip them, mothball and then unmothball-retrofit new advances and adding other components to fill spaces you've left?

Dweebs need to know this stuff.
