hi MPC,

thanks for your help, but "Ozeaneinstiegbehälter" is a very funny online-translation :-) for this into german. it's only an literal interpretation.
but according to your description i would like to say "Kaperschiff" (Captureship). another soure translate it as an command- and resceship.
it's not so easy... the same is for "boom defense vessel" in german.
