Not signed, because:
The ship itself is not any novelty or anything special shipbuilding-wise. It belonged to a very important person in research and I hope, the works of research are never forgotten. But the ship itself, is not anything special and has not ever been something special.
There are ships, that are far more worth to save than this one, worldwide.
If you want to see a really great preserved ship, which also everyone can visit and spend time onboard, go to Rotterdam and visit the SS Rotterdam, go to Hamburg and visit Cap San Diego. These are ships, which are really worth to save as worldwide importance for shipping.
Of course - just my opinion.
