you can go to poi database and look at all drop rates.(you can find the link in the drop reports category above the comments)

since it not in english you will have to memorise the kanji in case of a japanese ship, so it might be a pain

first you just click on the image of the map you are interested in, then pick a node, rank (A,S etc), and difficulty(in this order H N E) and below are the ships as well as drop info

but for the ones you mentioned the drop rates are:

prinz:       0.371%

pola:        0.506%

hayasui:   0.558%

you can find some more details on the site like drop rate for each enemy formation etc.
