Thanks for the quick answer!
I take it unique ships would provide ship size technology of the level needed to build them if scrapped for technology, right?
E.g. a 10cp unique ship could provide up to SS3.
This question did not come up in playtesting. So my answer is only 99% sure.
I see no reason why you could not scrap a Unique Ship to gain a Ship Size Tech Level. Provided that the Unique Ship took a Ship Size Tech Level greater than what you have researched to build.
Based on Jim and Paul’s posts I wish that I played more multiplayer games with Unique Ships and Boarding Ships. I could have my own “Rag Tag Fugitive Fleet”. Build 1 Unique Ship, capture 3 other Unique Ships from three Different Players, capture 2 more Unique Ships after the other players have done a redesign and then I am in control of 6 Unique Ships that are all different. Very silly, hard to pull off, but a big pile of counters in one hex.
