Sunlight is not good for your compass. The liquid inside gets cloudy over time, making it hard to read a heading. Most new compasses have covers to shield them from the effects of the sun when a boat is at rest. But there are times even when you’re not sailing that being able to see your “heading” is important.
We always cover our new compass on our Creekmore 34, Eurisko, when at anchor. But in unfamiliar anchorages we found we were continually taking it off in order to verify the direction we were facing. After removing the cover and then forgetting to put it back on a few times, my husband, Dave, came up with a compromise and cut a small slit in the front of the cover. That way most of the compass is still protected, but a small area is exposed so that we can see our heading. We can now check our relative position at a glance while still protecting our new compass.
