Maciek-Mark.
You are much better with organising the paperwork Maciek, thanks. We use the word Peilung Norwegian peiling just in the same way as the Germans. When it comes to larger amount like KM3 and oceandepth we use the word, sounding, like echolot sounding.
Some time ago I got a board, I guess from Maciek, showing the relation between rpm and speed for a VIIC together with the previous figures it might be of some help for checking the output, rpm, bmep and speed relations graph.
