The sub-science concept is one that sounds quite interesting. if they wanted to make the whole 'submerge' gimick different from a cloak they could technobabble it as reverse engineering the elachi 'hiding in subspace' tech.
I would like the new sci Risa ship to be able to clock by "diving into subspace" or something like that. you could call it subspace submerge you would need all 3 of the ships Universal Consoles, it could be a great Idea to use kinda of like what was done with the two Voth ships
here is an idea for a ships that could be used too
Comments
The racer/Corvette: Subspace Wake Generator
The Luxury Cruiser: Soliton Wave Generator
Risan Space Doff: Risan Drift
Summer Event Ship power: ??? (Vorticity? Shear instability? Flow? Current?)
I for one fully support Cryptic's references to the almighty power of Disco for it's land doffs.
A house boat? Like the Tuffli but much more... Risian in style?

seriously, i like very much the risian cruiser, can't wait to see the new risian ship
So a Risian Shuttle!
No giving them ideas would be...
concidering that this is Risa.. where would you "dock the shuttle"
Man even if it wouldn't be a "new" ship I so want that to be true...
(Science Vessel, of course.)
here is an idea for a ships that could be used too
