And of course all Sailors should have the Old Sailors Weather Station. It's a square piece of White sail cloth with a line in each corner to tie it to the rigging
. 4"x4" is OK, but the 6"x6" works better. To find out what the weather is doing, you take a look. If the cloth is dry, it ain't raining. If it is damp, it means it is drizzling. If it is wet, then it is raining. If it is just hanging, then there is no wind
and if it is flapping, then there is wind
. If you have to wear sunglasses when you look at it, then it is sunny. If you can look at it with just the eyes, it is cloudy. And the bonus is, if you can't see it at all, it's dark, errrr, or the wind was too strong.
