Checked with the neighbour again, the cat is complete and the last time it was inflated [<5yr] it was ok. The neighbour is in his seventies, that is the reason he wants to get rid of it. He approached me last friday when I was blocking the street with my car & trailer & cat [to bring it to the beach--finally] he said he saw me and the cat and figured I might be interested. It comes with a 2HP outboard as well [he figured the outboard was worth €50=+/-$65--that seems reasable]

I checked out the internet but very limited information is available on the boat, I found out that indeed it is made by Semperit the tyre manufactor

I will try to inflate the hulls before trying anything else
