In fact had done a mistake during the unzipping under MODS sub director.
Now the traffic on the Harbour exists (for the nautical licence is a great excercise

)
Two things remain out:
1_ have disalligneament between the "Course" cursor and the position of the U BOOT defined by the gognometer of 135° degrees and 500 mt. Thus the U BOOT is beyond of the Course cursor of 135° and 500 mt.
Is there a fix to use or .... made one other mistake??
2_ Still I don't have the mark of the hydrophone by the sonar man.
Is there a fix for that or is to be changed the set up?
