Hello together,

I'm a ship-loving guy from Germany and I'm very interested in small passenger ships serving coastal lines.
In Hamburg were operating two hydrofoils in the late 60s: Traf 1 and Traf 2.
Here is a picture of it in the port of Hamburg:

These ship were sold to Greece in the the year 1971.
Does anybody know anything about them?
Any information is welcome.

Thanks a lot and
best wishes from Germany,
Eike
