Summa Control

[Aahz]

Once a player obtains control of the Summa, does control remain with that player until/unless the other player gains control or does it revert back to no player controlling prior to a new ship activating?

Hello!

You check for control of the Summa-verminoth each time a ship activates.
A prior players control of the Summa-verminoth doesn't constitute current control when checking for control.
If nobody gains control, then no one has the control token and it remains neutral. The player that last had it doesn't continue to keep it, because they didn't gain control.
