Hello Frank
The CC19 is not fitted with built in buoyancy. There is very little wasted volume beneath the quarter berths, filling this space with rigid foam would help but would not give sufficient lift to keep the boat afloat in the unlikely event of being holed. There is a much larger volume below the forward V-berth, useful buoyancy could certainly be fitted there, but you would lose the storage facility it offers. If the boat were holed in that area the flood should be contained anyway by the bulkhead (at the aft end of the space).
Buoyancy could also be fitted at the aft end beyond the quarter berth cushions and either side of the outboard well.
One of the advantages of the CC19 is that virtually all of the internal volume is available as useable space.
To return to your question, "does anybody knows whether the CC19 is sinkable or not?". I imagine if you drilled a hole in the hull, it would sink. However, the boat is robustly constructed, and I do not know of any which have sustained sufficient accidental damage to sink them.
