Default Sun Compass Skills

Here's the situation: You're 100 miles offshore and bailing to the
liferaft. You've become disoriented and have lost your bearings. You
reach for the GPS-12 and find it's DOA. Among your options is the sun
compass. Do you know how to make and use one?


Yes. Do you?

To make an accurate sun compass requires an almanac and a
watch. With a protractor, you could improvise if you had a
good idea of the current declination of the sun.

It's based loosely on the concept that the sun rises in the
east and sets in the west, and at local noon will be either
directly south or directly north, depending on which
hemisphere you're in. With a protractor, you can draw angles
on a card (or directly on the deck) and interpolate
direction between sunrise and sunset.

Now, can you do the same thing for the moon?
