I was a child of the pencil-line on the chart. As QM in the CG my job was to maintain the plot on the chart.
The first time I sailed mate on an Aleutian freighter with no gyro stabilized radar or EBL/VRM was an adjustment.
When the only reliable compass failed, the gyro, it was a “you’re not in Kansas anymore” moment. Neither the captain nor the owner understood why I was complaining about the lack of a compass.
Five (stressful) days later I was OK with it too.
Edit: not really five days, maybe 3 days of high stress and slowly lower. It wasn’t till I made one full trip (20 days) that I was really used to working without a compass, It’s really mostly (but not entirely) about local knowledge
