Hi Doug The compass is filled with Kerosene or similar. I don't think it will freeze. On airplanes the temperature is also below freezing and I have never observed any ill effects. One idea is to have a separate hatch board just for the compass. Then when you lock the boat up you can keep the compass down below out of the sun and weather.

I have put "umbra limi" to bed for the winter. As an afterthought I am wondering if I should have pulled the compass from the hatch-board. It is a Saturn 140a bulkhead mount type. I cannot find the literature for the compass which would give me the temperature tolerances. I can expect to get to 10 below here in the midwest if it is a bad winter. For those of you in the cold climates do you leave or pull your compasses for the winter? Thanks for any advice!
