Been playing some more...
The graticule in the periscope view as you rightly say, goes from 0-360. In Brit boats, one thinks in left and right, or red and green. So you're either looking somewhere left - red, or somwhere right - green. A contact will be at green 120 for instance (on your starboard quarter), of red 35 (on your port bow). So, a direction in terms of degrees will never exceed 180, in either direction.
There's also a problem in navigating. Maybe not "problem", because the designers may well be using conventions which are current in, for instance the US navy. However, the chart clearly is "north-up", ie north is upwards. However, when you overlay a compass rose, it seems to show north pointing downwards. Hellishly confusing! And in the first bit of learning, the lookout says "ship bearing 209 degrees (or something like that) which should place it south west of the boat, but it isn't, it's off to the north west.
It all probably wouldn't confuse me at all if I hadn't spent years in boats!
