thanks all very much for your help and the welcome !
just a few things on my return.....
on approach to the north sea end of Kiel canal as i was leaving on patrol i was repeatedly fired upon by land guns and then a few boats - had to dive to P. depth to get away !!
then i went off for some dinner ( in my own world..) leaving my crew on watch, then an almighty
CCRRUUNCHING sound came through the speakers, only to discover i had been rammed by a small merchant !!!!
everthing is alright now after dropping my knife and fork - wine glass slops onto the table, and did a swift avoidance manouver!!
also a couple of CTD's but they seem to have settled out.....crikey blimey,
got im himmel!! and all that.....some return !!!
cheers all, see you out there !!
